Question 1

How many watts are in a lumen?

Accepted Answer

Lumens and watts represent different quantities, so you cannot convert lumens to watts. But once you know the luminous efficiency of a lamp, you can use lumens to deduce the wattage of the lamp. For example, if the luminous efficiency of a 15000lm street lamp is 150lm/W, then we know through calculation that the lamp is 100W.

Question 2

How equals to 100w incandescent?

Accepted Answer

It's easy to estimate the brightness of an incandescent bulb. Generally, the higher the wattage rating, the more light it puts out. For example, a 60-watt incandescent bulb puts out 900 lumens, which is equivalent to a 7-9W LED bulb. A 100-watt incandescent bulb puts out 1500 lumens, which is equivalent to a 12-14W LED bulb. ( Please review case studies of 100w LED street light. )

Question 3

How many lux can your light(10000lm) reach?

Accepted Answer

When all conditions are the same, the lumen and lux of a lamp are positively correlated.

However, when the light distribution of the lamp, the installation height of the lamp, and the illuminated surface are different, there is no necessary connection between lumen and illumination. For example, 10,000 lumens, concentrated on an area of 500 square meters, the illumination obtained is 20 lux. The same 10,000 lumens, if irradiated on 100 square meters, the illumination level produced is 100 lux.
