Watts to lumens Conversion Calculator

Converting watts to lumens requires the following formula:

lumens = watts × (lumens per watt)

Incandescent bulb (12-18 lm/W)	Lumens (lm)	LED bulb (90 lm/W)	Halogen (23 lm/W)
25 W	300-450 lm	3-5 W	15-22 W
40 W	480-720 lm	5-8 W	23-35W
60 W	720-1080 lm	8-12 W	35-52 W
75 W	900-1350 lm	10-15 W	44-65 W
100 W	1200-1800 lm	14-20 W	58-87 W
