FAQ - How many watts of LED bulbs do you need in a room?

Since we confuse watts with lumens, it's easier to talk about bulbs in watts. So if a 100-watt incandescent lamp produces 1,500 lumens, and a 10-watt LED produces the same effect, a 10-watt LED might advertise "100-watt equivalent" on its label.

For example:

ROOM	FOOT CANDLES NEEDED
Hallway	5-10
Bathroom	70-80
