150lmW
150lmW refers to a luminous efficacy rating, indicating the efficiency of a light source. The unit signifies 150 lumens per watt. Lumens (lm) are a measure of the total amount of visible light emitted by a source. Watts (W) are a measure of electrical power consumption. Therefore, 150lmW means that for every watt of electrical power consumed, the light source produces 150 lumens of light.
This metric is particularly relevant in the context of lighting technologies, such as LED bulbs, fluorescent
The adoption of high lmW lighting solutions is driven by the desire to reduce energy consumption and
