Led 18W is equivalent to 40W energy-saving lamp.
2. The light efficiency of 2.Led lamps is also higher than that of energy-saving lamps, which can reach 130Lm/W at the highest with current technology, which means it is very bright.
3. From the opposite eyes, many Led lamps have achieved the index of 80, that is to say, the reduction rate of light and substances in the sun is above 80, while energy-saving lamps are only 60-70. Three-color lamps of energy-saving lamps can be realized, but there are still heavy metal gases.
