Energy efficiency

How energy efficient is a lamp?

Light output is indicated in lumens/watt (lm/W) and is a measure of efficiency.

Lm/w tells how efficiently a product converts electrical energy into light. High lumen per watt results in low electricity consumption and therefore a longer battery life.

Watt (W) is the standard unit of power, where one watt corresponds to an energy conversion of ​one joule per second.
