What is 400 lumens equivalent to?
400 lumens of light is given off by a 40 watt light bulb. 400 lumens is equal to 37.161216 foot-candles or 400 candelas. Since a candela is approximately equal to the light given off by 1 candle, 400 lumens gives off about the same amount of light as 400 candles combined.
How many lumens is equal to one watt?
