Recessed Lighting Lumens Per Square Foot

Light bulbs and some lighting fixtures carry a specific lumen value.

Recessed lighting lumens per square foot.

For general lighting purposes you ll want to provide 1 5 watts of lighting per square foot of space in the room. For the average space of 250 square feet you ll need roughly 5 000 lumens as your primary light source 20 lumens x 250 square feet. Commercial spaces like retail stores can utilize many of the same light types but they may not require the same number. L 538 2 4 1291 lumens.
