"If your home is 40 watts of incandescent lamps, then replace a 15-watt energy-saving lamps, you can achieve the same lighting effect. If the home are using energy-saving lighting products, you can save at least 30% of electricity consumption!" A few days ago, the provincial energy-saving association secretary-general Li Yanzhi said the province this year will continue to promote high-efficiency lighting products in the form of financial subsidies, and will be more than 1 million! At the same time using a variety of ways to promote the use of energy-saving lighting products.
A few days ago, the National Development and Reform Commission decided, in order to accelerate the promotion of energy saving and emission reduction, the Development and Reform Commission has launched the "China to phase out incandescent lamps, accelerate the promotion of energy-saving lamps action plan" preparation. Xie Zhenhua, deputy director of the NDRC, said that the Chinese government has cooperated with the United Nations Development Program and the Global Environment Facility to carry out the "phasing out incandescent lamps and accelerating the promotion of energy-saving lamps" project, which supports Chinese incandescent lamp producers to switch to energy-saving lamps.
Li Yanzhi said, the Ministry of Finance and the National Development and Reform Commission from 2008 onwards through financial subsidies, the promotion of 50 million high-efficiency lighting products, including bulk users such as industrial and mining enterprises, office buildings, hospitals, schools, commercial buildings, hotels, etc., each high-efficiency lighting products, you can enjoy 70% discount, the central government in accordance with the agreement to win the bidding of the price of the supply of 30% to the enterprise subsidies; to the street, community committees as the purchasing unit. Streets, community committees for the purchase of units of users, each high-efficiency lighting products, you can enjoy a discount of 50%, the central government by the bidding agreement to supply 50% of the price of corporate subsidies; ordinary consumers to the designated shopping malls to buy the designated energy-saving lighting products, will enjoy a 50% discount, with an ID card and household registration each person can buy up to seven.
It is understood that in 2006, a study by the International Energy Agency, if from now on in the world to phase out incandescent lamps, by 2030 the world can save 38% of the lighting electricity, carbon dioxide emission reduction of 16.6 billion tons. Li Yanzhi said: "Overall, the eastern provinces of the energy saving work done better than the western provinces, popularization efforts. China's annual sales of incandescent lamps reached 2 billion, small and medium-sized cities, residents of incandescent lamps are generally used in the proportion of more than 50%, the use of energy-saving lamps in our province, the ratio is relatively low, in our province, if all of us use energy-saving lamps, will save 3.6 billion kilowatt hours of electricity per year, and I hope that more enterprises, institutions, communities and ordinary consumers to devote themselves to green energy-saving campaigns!"
Shopping tips
Buy energy-saving lamps don't forget to check the energy efficiency label
Currently, there are many varieties of energy-saving lamps on the market, the price difference is very large, how to choose and correctly use energy efficient products? According to Opple Lighting North Daminggong store manager Li Zhaqi introduction, in addition to focusing on the brand, packaging, appearance and other relatively easy to see the judgment criteria, buy energy-saving lamps to seize the "energy labeling" and "energy-saving experiments" two issues. "Regular brands will give consumers to do a 'comparison box experiment', usually, 5 watts of energy-saving lamps and 25 watts of incandescent lamps produce the same lighting effect, in the comparison box, the two lamps were illuminated a bouquet of flowers, by judging the brightness of the object, you can judge the two lamps of the lighting Effect." Li Zhaqi said, the country has introduced energy-efficiency standards for energy-saving lamps and lanterns, to meet the standards will have energy-efficiency labels, the average life of more than 8,000 hours of energy-saving lamps and lanterns products can be issued, in the quality inspection report of the product can be found out.
Quality qualified energy-saving lamps, if used 4 hours a day, can be used for 4 to 5 years. Currently high-quality energy-saving lamps warm light design is also very diverse, yellow, blue, red, green are available, consumers can be based on personal preferences, choose to match the color of the light and home design. Choose to the satisfactory energy-saving lamps and lanterns, do not rush to pay, the general stores will provide lamp base to consumers to test lamps, try before payment to ensure that the operation of the energy-saving lamps are normal. Lamps in the power, you should also pay attention to it, phosphor coating thickness is uniform, which will directly affect the normal lighting effect of the light.
Light and shadow design
With the "light health" to create the mood of the room
In the room, we must pay attention to the reasonable matching of light sources, to avoid or reduce the interference of glare, so that the "soft" light warmth of our lives. Yuanzhou decoration designer Yan Kelun said, how to reasonably match is also a lot of learning.
Living room is best not to use harsh glare
Living room is the focal point of the family part, a lot of activities, in the roof or background wall pre-lighting slots, hidden fluorescent tubes, you can create a completely different from the daytime dreamy romantic feeling. Yan Clun said that if the living room lights are bright, it is easy to produce harsh glare, making people feel uncomfortable. Can be arranged on the wall with the interior decoration style consistent with the wall lamps, quartz spotlights, so that it illuminates a wall, issued with a calm and neutral indirect lighting effect, cozy and warm.
Looking at writing assignments in the dark is easy to cause myopia, there can not be too much glare in the study, the study is generally installed in a ceiling lamp and a desk lamp, the tone with warm colors.
Bedroom lamps to make a sense of relaxation
Dining room light source to the food color reduction, adding warmth and romantic mood. Dining room is suitable for the use of good color rendering of the warm tone of the chandelier, crystal lamps, can be free to lift better. If limited by space, you can choose compact wall lamps with top downlights for processing.
Bedroom to consider the actual lighting needs: local lighting, such as dressers, closets, reading lighting around the bed, etc., the need for brighter, warmer light. Yan Klun said, the light color of the light source in the bedroom lamps and lanterns is best to use a relaxing kind of color tone, and with the combination of local lighting, for the whole bedroom to enhance the atmosphere.
Kitchen fixture use and safety
Kitchen is the home of the busiest, most labor activities, this area should focus on the practicality of lighting, so that the fun of the kitchen and safety. Kitchen lighting is mainly set directly above the operating table to illuminate the large piece of the operating table below, the lamps and lanterns light source color rendering should be good, in order to truly restore the food color. It is worth mentioning that the bathroom light time will not be very long, so it is not appropriate to install energy-saving lamps in the bathroom, because frequent opening will reduce the life of energy-saving lamps.
Energy-saving lamps have energy-saving, soft light and other advantages, favored by consumers. But the free energy-saving lamps market is a mixed bag, how to buy their own energy-saving lamps in a wide range of lamps in the lighting store? This requires an understanding of the energy-saving lamps junction, parameters and other basic indicators.
Currently on the market energy-saving lamps are mostly compact (CFL), small size, socket and incandescent lamps are completely unified. General energy-saving lamps are classified according to the shape of the lamp: with the English alphabet pictorially named, for example: H-shaped, U-shaped, D-shaped, spiral and so on. Different shapes to adapt to different assembly needs, some also in the lamp outside a transparent or sand cover, used to protect the lamp, so that the light is soft.
The basic parameters of energy-saving lamps are divided into two categories of light parameters and electrical parameters. Users in the purchase of energy-saving lamps should focus on understanding the following.
1, power (P) size reflects the size of the lamp power consumption. Specifications from - 36W ranging from a few square meters of small area lighting with 9-13W is more appropriate, the power of these energy-saving lamps in the process is more mature, relatively cost-effective. 10 square meters of room lighting can be used more than 32-36W straight-shaped energy-saving lamps.
2, power factor 〈COSΦ〉 research has proved that the lower the power factor, the lamp ends are more likely to be prematurely blackened; shorten its service life. Good quality energy-saving lamps, power factor can reach 0.9 when above. Brand-name manufacturers of larger power energy-saving lamps using power factor correction (A-PFC〉technology, its power factor is higher, almost close to the pure resistance.
3, the total current harmonics (THD) should generally be below 50%, the smaller the value of the harmonic current is smaller, the use of high-frequency interference generated by the smaller.
4, luminous flux and luminous flux maintenance rate: the former reflects the luminous efficiency of the lamp, the greater the value of the better; the latter indicates the aging of the lamp; generally 2000 hours after the maintenance rate should be more than 80%.
5, color index 〈Ra〉 general between 63-85; the larger the value of the lamp emits a spectrum closer to natural light. Other parameters are many, such as crest factor, start-up time, color tolerance (SDCM), etc., in the face of these parameters, how to choose energy-saving lamps? The author puts forward the following suggestions for reference when purchasing.
<1>Select the Great Wall logo or by the safety certification of the production side. Such as Philips (PHILPS), the United States General (GE), Germany Oseland (OSRAM), Weihai Beiyang, Sunshine Group, Far East, Jianhu, on the power, Siyang bulb factory, etc.; choose the packaging is exquisite, exquisite appearance, manufacturers address, telephone and technical manuals and other complete products is also very important.
<2>Look at the starting performance. Purchase if there is a regulator is the best, power outage first regulator to 150V (according to the minimum starting voltage indicator listed in the manual), loaded with a naturally placed energy-saving lamps, hands and body away from the lamp, turn on the power supply is best able to ignite at once. Because the energy-saving lamps start two characteristics: first, the higher the temperature of the start the easier; second, in the human body to sense how easy to start. It is worth mentioning that many energy-saving lamps open that is bright, which is unfavorable to the life of the bulb, energy-saving lamps should be equipped with a filament preheating circuit inside the start time of 0.4 seconds or so of the delay time, so "a gray lit" should be understood as a start-up flickering small, the lamp should not appear inside the phenomenon of reddening.
<3>Look at the interference inertia. Electromagnetic compatibility is an appliance must have the performance. Users to buy, should check whether the box has passed the national electromagnetic compatibility test logo.
〈4〉 Energy-saving lamps in normal operating conditions, the temperature rise should be very low. Otherwise, the energy-saving lamp life is very short. At the same time, the energy-saving lamps lit, the lamp ends black, filament red or flashing, are indicative of the energy-saving lamp quality problems. 〈5〉 Appearance acceptance. Energy-saving lamps plastic shell must be made of flame-retardant engineering plastics, ordinary plastics are prohibited for the production of energy-saving lamps. In addition, from the lamp, you can put more than one lamp together to compare the shape of the lamp and only inch consistency is better than the mass production of products, quality is guaranteed. At the same time, the shell can not have cracks, loose, the seal should not be pried traces.
Buy reminders
Buy energy-saving lamps to see the two major signs
Related experts said that consumers in the purchase of energy-saving lamps, not only to pick a well-known brand, but also to see whether there is a "cqc" and "section" of the word mark. The word mark. "cqc" is a safety certification mark, indicating that the product is recognized by the China Quality Certification Center; "section" is the energy-saving certification mark, indicating that the product is recognized by the China Energy Conservation Product Certification Center, which is the energy-saving lamps performance indicators and the national energy-efficiency limit value of the verification. In addition, electronic energy-saving lamps on the packaging should also be energy-saving lamp life, color rendering, the correct installation location to make instructions. After opening the package, the energy-saving lamps should also have some necessary signs, such as power supply voltage, frequency, rated power, the name of the manufacturer and trademarks.
How to buy energy-saving lamps
Choose products with authoritative certification mark
Safety certification --- for the "CQC" mark, the mark of the product that the product is recognized by the China Quality Certification Center, in line with the China Lighting Industry Association. China Quality Certification Center approved by the China Quality Certification Center, in line with the provisions of the safety requirements of the China Quality Certification Center, is the verification of the safety indicators of energy-saving lamps.
Energy-saving certification --- for the "section" mark, the mark of the product indicates that the product is recognized by the China Certification Center, in line with the energy-saving requirements set by the China Certification Center, is the energy-saving lamps performance indicators and the verification of the national energy efficiency limit value. The verification of the national energy efficiency limit values.
Look at the packaging
The state mandatory requirements for energy-saving lamps products, marked on the outer packaging of the following: source logo, rated voltage and voltage range, rated power, rated frequency. On the lamp, packaging, or in the instruction manual labeled on the lamp current, and other additional instructions related to safe use.
Understanding the energy-saving lamp model
such as an energy-saving lamp product model: YPZ230/9-3U-RR-D 6500K, where YPZ represents the general lighting self-ballasted fluorescent lamps (energy-saving lamps), 230/9 that the rated voltage 230V, rated power 9W, 3U that the structure of the lamp (consisting of three U-shaped tube), RR that the lamp's Luminous color, D that electronic self-ballasted, 6500K that the relevant color temperature or expressed in Chinese into daylight color. General energy-saving lamp products labeled with the first three more.
Choose the model of energy-saving lamps
Power --- lighting effect is the same, the power of energy-saving lamps for incandescent lamps one-sixth. Therefore, if you want to get the same lighting effect as 60W incandescent lamps, choose 10W energy-saving lamps can be.
Luminous color --- mainly based on the use of the environment and personal preferences. In the bedroom, dining room and other warm places can be purchased marked with RN, RD letters or warm yellow and other words of the energy-saving lamps, and light-emitting color yellowish energy-saving lamps of its luminous efficacy, color rendering index is higher than the light-emitting color of white energy-saving lamps. Some consumers believe that the light-emitting color of the more white or even hair "blue" lights the brighter, is a misunderstanding.
The appearance of energy-saving lamps to choose
One look at the head, whether the lamp is loose, the lamp phosphor coating is uniform without leakage, powder, phosphor should be crystal white, can not have the phenomenon of yellowing or gray.
The second look at the power to light up the lamp, the lamp light is normal and uniform, the lamp should be no obvious black spot, the luminous body does not flicker.
Pay attention to the interchangeability of the lamp
Interchangeability is the product of the lamp head and lamp base can be good with the indicators. Interchangeability is not good will cause the light installation and disassembly difficulties, so that the lamp can not be reliably fixed in the lamp base, resulting in unsafe hidden danger.
In addition, consumers in the purchase of lamps and lanterns, try to buy brands of energy-saving lamps between the generality of the product, in order to prepare for the future convenient replacement of new lamps.
Carefully read the manual
Carefully read the product manual and the text on the package, which can not only guide the correct use of energy-saving lamps, but also to learn more about the product's other properties, such as the power factor, luminous efficacy, etc., which is conducive to consumers to understand the product quality situation.
8, for you to calculate an account, if you choose energy-saving lamps, you can save how much money.
To a two-room residence, for example, choose to meet the national standards of the product, the use of the cost is as follows:
A. If you meet the normal lighting, you need to use about 30 incandescent lamps 25W specifications. Each price of 2 yuan, according to the use of time accumulated 6,000 hours (about two years) to calculate the cost is as follows:
1) Purchase bulb costs: 6,000 hours of use, due to the life of the product *** need to replace the bulb 6 times. The cost of 30 × 2 × 6 = 360 yuan
2) Electricity: 6000 hours of use, calculated at 0.5 yuan per kilowatt-hour, *** to pay for electricity [(25 × 30 × 6000)/1000] × 0.5 = 2,250 yuan
3) two-year cost *** for 2,610 yuan
B. If you use energy-saving lamps, when to achieve the same light output with the use of incandescent lamps, it is only necessary to use the same light output with the use of incandescent lamps, the cost of the lamps will be reduced. B. If you use energy-saving lamps, when you achieve the same light output as incandescent lamps, you only need 30 energy-saving lamps with a size of 5W, at a price of 15 yuan each
4) Purchase of bulbs cost: 6,000 hours of use (about two years) without replacing the energy-saving lamps. The cost of 15 × 30 = 450 yuan
5) Electricity: 6,000 hours of use, calculated at 0.5 yuan per kilowatt-hour, *** to pay for electricity [(5 × 30 × 6,000)/1,000] × 0.5 = 450 yuan
6) two-year cost *** for 900 yuan
From the above calculations, we can see that, if you choose the right one, the two years can save nearly 1700 dollars or so.
In home improvement, people attach great importance to environmental protection and energy saving. Energy-saving lamps are more widely used, about energy-saving lamps, "power saving does not save money", "energy saving does not protect the eyes," said the experts, do not rule out some unscrupulous, the conditions do not have the manufacturers to produce energy-saving lamps out of the quality is not satisfactory, but into the market, but As long as you do enough work, buy to the positive scale manufacturers, the real energy-saving energy-saving lamps, and the correct use, "power saving does not save money", "energy saving does not protect the eyes" and other issues mostly do not exist. Energy-saving lamps on the market in many models, and prices vary greatly, some only need 8 yuan a, some need more than 20 yuan a. In the various types of lamps. In front of a variety of lights in all shapes and sizes, how can consumers choose to cost-effective energy-saving lamps? Look at the experts for your tips.
One, look at the brand to recognize the logo
Experts, first of all, according to the size of the use of the environment and the requirements of different levels of illumination, the choice of different power specifications, luminous flux and life expectancy of the lamp. The easiest way to buy energy-saving lamps is to choose a well-known brand of products, consumers can refer to the national government procurement of qualified suppliers directory, from which to select a well-known brand, and specializing in the operation of lighting malls or lamps and lanterns franchise purchases. So that both sides of the sales have a clear responsibility for supply and sales, are generally more secure.
CQC (safety certification) mark or a report involving safety certification can only indicate the safety of the energy-saving lamps, does not mean that the performance and energy efficiency of the product meets the relevant requirements, so consumers in the purchase of energy-saving lamps, but also should require the business to provide the performance and energy efficiency of the inspection report, the two reports to view the lifespan of energy-saving lamps, light efficiency and other parameters.
Two, check the information view appearance, hands-on experience of quality
Consumers can also be samples, products, packaging and instructions on the information to test the quality of the product: including information about the manufacturer, the relevant indicators, the product implementation standards and so on. To pay attention to the source of the product is true. This information should be clear and easy to recognize, attached firmly, the handwriting, pattern shall not be blurred, overlap.
View the appearance of energy-saving lamps is also the most common test of its quality, the most important one: good energy-saving lamps should be smooth appearance, no air bubbles, the phosphor coating inside the lamp should be fine, no particles, was uniformly white; lamp head and lamp should be vertical, there should not be tilted; lamp head and the power supply should be flat on the contact surface.
In addition, the package should have relevant measures to prevent damage to the lamp.
In addition to product information and packaging, consumers can also test the quality of energy-saving lamps: clockwise, counterclockwise direction of the rotating lamp head, observe the lamp head and the lamp body whether there is loosening, and shake the energy-saving lamps with their hands, if the lamp and the plastic parts of the link between the solid will not have rattling.
Consumers can also check the energy-saving lamps on the power: 5 seconds after the light, and then off 55 seconds, observe the filament black and yellow, generally no black and yellow energy-saving lamps are better. In addition, consumers can also observe the lamp at the moment of power on the luminous situation. Under normal circumstances, the lamp luminous first a little dark, a few seconds later, suddenly became very bright, such a lamp than a power immediately after becoming very bright lamp life longer.
For non-famous brands of lamps, consumers can use a well-known brand of high-quality products as a sample, in the light and not the light of the two cases, the phosphor coating of the lamp, glass tube, lamp, plastic parts to do a comparison, if the feeling is appropriate, you can rest assured that the purchase.
Experts, energy-saving lamps and incandescent dimensions are similar. In the same situation, the consumption of electric power is only incandescent 1/4, but the life of an incandescent 6 to 8 times, in addition to energy-saving lamps than incandescent surface luminescence is also softer than the incandescent lamp is the ideal incandescent replacement. In addition to spotlights, in all places where incandescent lamps can be replaced by energy-saving lamps.
But turning on the current several times in a short period of time can easily damage the life of CFLs. If you need to go in and out of a room many times in an hour, it's best to put away the good habit of "turning off the lights as you go" for a while.
Additionally, experts remind consumers that improper use of energy-saving lamps can also cause energy-saving lamps, "saving electricity does not save money," most of the current energy-saving lamps are not suitable for use in dimmable lamps and lanterns, and is not suitable for installation in the lamps and lanterns that rely on the sound and light control switches, the consumer is best to read the instructions carefully before installation. In addition, the voltage is too high or too low will affect the life of the energy-saving lamps, the best choice of voltage range is 220V lamps, its life is more long.
As for the "energy-saving does not protect the eyes", experts said, energy-saving lamps do not exist on the human eye harmful to the argument, just some embedded downlight diameter depth is too shallow, lamp protruding, the light of the lamp will stimulate the human eye, bring harm, this type of lamps and lanterns can not be selected. Consumers should also choose the style of energy-saving lamps according to the type of lamps. As long as the lamps can meet the requirements of the relevant standards, there is not much problem.
And the use of energy-saving lamps, but also pay special attention to environmental issues. Can not use the energy-saving lamps can not be thrown anywhere. Energy-saving lamps are glass products, the lamp inside the use of trace amounts of mercury, so we must be light to avoid rupture, caused by the glass broken or mercury diffusion will cause personal injury.
Energy-saving lamps are increasingly popular because of their obvious power-saving effect, long service life, no strobe effect, no noise, and a wide range of operating voltages. Currently on the market a lot of energy-saving lamps, we are buying, how to distinguish between the advantages and disadvantages of energy-saving lamps?
Purchase should pay attention to the following points: First, to see if there is no national inspection report;
Two is to see the product packaging, including the product's trademark, the nominal power, the contents of the mark, wipe with a soft damp cloth, the logo is clearly distinguishable that is qualified;
Three is the service life of qualified energy-saving lamps in experimental condition up to 5,000 hours or more, when in normal use Must reach more than 2000 hours, such as less than this standard, that is, inferior products; four is the safety requirements, in the installation, disassembly process, to see whether the lamp head is loose, there is no crooked head phenomenon, whether the insulation; in addition to this, look at the energy-saving lamps outside the tube material is heat-resistant, fire-resistant, the lamp in the phosphor is uniform. If not used on the phenomenon of blackening at both ends of the lamp, are unqualified products; there is another point is the price comparison, in general, due to the energy-saving lamp manufacturing, production process of special reasons, the cost is relatively high. If it is seven or eight dollars of energy-saving lamps, it is likely that some small factory production of poor quality, the general price of domestic energy-saving lamps are more than forty or fifty dollars, imported is even higher.
Shopping:
General note is: first, buy those recommended by the safety certification and national green lighting project products, do not buy three products; second, the appearance of the inspection, pay attention to the lamp and the shell is not loose, whether the phosphor is uniform, whether the particles are present, the thickness of the lamp should not be too large a change. A good product also depends on the correct use to extend its life. We should pay attention to the use of energy-saving lamps: do not switch on and off frequently; to let the energy-saving lamps work in the ambient temperature of 0~50oC. And people always like to install the energy-saving lamps in the downlight inside the use. Due to poor heat dissipation conditions, the energy-saving lamps and electronic components of the high temperature performance requirements (we have done tests, the temperature inside the molded parts at this time can be as high as 90-105 ℃). So it is best to choose a larger size in the selection of downlights, do not block the energy-saving lamp cooling holes, so that it leaves enough space for heat dissipation.
1, many consumers buy energy-saving lamps to always use the tungsten bulb power as a reference. Most manufacturers will list the power of the product itself and the power of the tungsten bulb against which the luminosity is comparable on the package. For example, on the package there is a "15W → 75W" logo, generally refers to the actual power of the lamp is 15W, claiming that it can emit a tungsten bulb with a luminosity similar to a 75W. 2, some of the products in the packaging of the Electrical and Mechanical Services Department issued by the energy-efficiency labels. Manufacturers have to ensure that the energy saving lamps meet safety specifications, reach a certain level of light readiness, and have an average lifespan of more than 8,000 hours before they can be issued with the label, which provides a certain degree of quality assurance. 3. Some energy saving lamps are available in white light and yellow light colors. Generally people psychologically feel that white light is colder, yellow light is warmer. To compare the different colors, you can go to the showroom appreciation. Users can choose according to personal preference, and home furnishings with the color of the light. 4, the test sample of the lamp and the plastic base loose, consumers should be careful to check the structure of the energy-saving lamps when purchasing. Some stores provide lamp base for consumers to measure the lamp, try before payment to ensure that it operates properly. 5, (non-civilian energy-saving lamps) in the purchase of energy-saving lamps, but also consider the technical parameters of the electronic ballasts, such as harmonic content, power factor, whether or not equipped with filters and other indicators. Especially some large areas, large quantities of energy-saving lamps occasions, be sure to choose low harmonics, high power factor, with filter parts of the energy-saving lamps, and try to install more power switch, to avoid due to a large number of energy-saving lamps at the same time switch, by the high voltage impulse of the power grid impact, and damage. 6, the whole lamp of the plastic shell, you should choose the high temperature flame-retardant plastic shell? Shell is matte. 7, pay attention to observe the lamp in the power, whether there is due to the uneven thickness of the phosphor coating and affect the normal illumination of the light phenomenon.
How to identify the three-color lamps and halogen lamps?
General users in the purchase of the following points:
1, three-color energy-saving lamps, the appearance of the more delicate, plastic parts are usually made of flame-retardant materials to withstand high temperatures; halogen lamps are shoddy products, the appearance of the rough, simple circuits, components inferior, and even more plastic parts are not flame-retardant, the use of hazardous.
2, three-color energy-saving lamps, lit a few minutes later, only to reach normal brightness, both bright and soft; and halogen lamps are shoddy products. Both bright and soft; and halogen lamps, once energized, the brightness of the basic peak, low brightness, light color green, pale and weak. 3, to introduce a simple identification method, will light up the three-color lamps, light on the palm of their own hand, the palm of the hand appears to be red and blood; the same halogen lamps light on the palm of the hand, it appears green, no blood. When the two lit lamps are placed together to compare, the difference is obvious.
