The LED luminous efficiency is 100 LM / W and light transmittance of bulb Lampshade is 75%. The power factor of our company’s products is above 0.9, so the luminous efficiency of our LED lights is 100 * 75% * 0.9 = 67.5 lumens / watt.
The emitting efficiency of incandescent lamp is 6.5 lm/w - 15 lm/w. The ordinary luminescence efficiency is 10 lm/w. The incandescent lamp is made of transparent glass, so the light transmission rate can be seen as 100%. At the same time, the power factor of incandescent lamp is 1, so that the luminous efficiency of that is 10 lm/w. Here are the results of comparison luminescence efficiency between LED bulb and incandescent lamp: LED bulb lamp and incandescent lamp = 67.5 LM / W 10 LM / w = 6.75The above formula illustrates that a 6.75 watt incandescent lamp can be replaced by a 1 W LED bulb lamp. Then 5W LED bulb lamp can replace the 33.75 watt incandescent lamp; A 7W LED bulb lamp can replace the a 47.25 watt incandescent lamp.
