For example, if the area of ​​the walk-in closet is 6 square meters, the total lumen value required is: ● 6 square meters × 250 lumens (lumens per square meter) = 1500 lumens ● For an 8 square meter closet, the total lumen value required is: 8 square meters × 250 lumens = 2000 lumens If the area of ​​the closet is larger, LED light bulbs with stronger light sources or more lamps may be considered to provide sufficient lighting.

Luminous efficacy (lm/W) = Luminous flux (lm) ÷ Power (W) For example, if the luminous flux of an LED bulb is 800 lumens and the power is 8 watts, its luminous efficacy is: Luminous efficacy = 800 lm ÷ 8 W = 100 lm/W
