Formula
Watts = Lumens / Efficiency(lm/W) | Lumens = Watts x Efficiency | LED ~90 lm/W | CFL ~60 lm/W | Incandescent ~14 lm/W
Frequently Asked Questions
How many lumens is a 60-watt bulb?
A traditional 60-watt incandescent bulb produces about 800 lumens. To get the same brightness from an LED, you only need about 9-10 watts. A CFL would use about 13 watts for the same 800 lumens.
How do I choose the right LED bulb brightness?
Look for lumens, not watts. For a 40W replacement, look for 450 lumens. For 60W, look for 800 lumens. For 75W, look for 1,100 lumens. For 100W, look for 1,600 lumens. The lumen count is printed on every bulb package.
