According to the light efficiency of LED lamps on the market at present, the luminous flux of 100Lm/W, 3W is 300Lm；; The light efficiency of energy-saving lamps is about 60Lm/W, 300 ÷ 60 = 5, so a 3W LED lamp is equivalent to a 5W energy-saving lamp.
Extended data
Advantages of led lamp
1, high efficiency and energy saving
Only a few kwh of electricity is consumed in one thousand hours (ordinary 60W incandescent lamp consumes 17 hours 1 kwh, and ordinary 10W energy-saving lamp consumes 100 hours 1 kwh).
2. Long service life
The semiconductor chip emits light, has no filament, no glass bubble, is not afraid of vibration and is not easy to break, and its life can reach 50,000 hours (the life of ordinary incandescent lamps is only 1000 hours, and that of ordinary energy-saving lamps is only 8,000 hours).
Step 3 be healthy
Light health lamp does not contain ultraviolet rays and infrared rays, and does not produce radiation (ordinary lamp contains ultraviolet rays and infrared rays).
4. Environmental protection:
It does not contain harmful elements such as mercury and xenon, which is beneficial to recycling and will not produce electromagnetic interference (ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps will produce electromagnetic interference).
5. Protect your eyesight
DC drive, no stroboscopic (ordinary lamps and lanterns are driven by alternating current, which will inevitably produce stroboscopic)
6. High luminous efficiency
10% of low-heat electric energy is converted into visible light (95% of electric energy of ordinary incandescent lamps is converted into heat energy, and only 5% of electric energy is converted into light energy).
7. High safety factor
The required voltage and current are small, the heating is small, and no potential safety hazard is generated. It is used in dangerous places, such as mines.
8. Huge market potential
Low voltage, DC power supply, storage battery, solar power supply, remote mountainous areas and outdoor lighting and other places lacking electricity.
