How many lumens should an LED flush mount ceiling light have?

Plan about 10 to 20 lumens per square foot of floor for general light. A 120 square foot bedroom needs roughly 1,200 to 2,400 lumens. A 200 square foot room needs roughly 2,000 to 4,000. This is common retail lighting guidance, not a measurement of one 51lighting fixture. Read listed lumens. Watts do not tell you brightness.

Room Example area General-light target
Small bedroom or hall 80 sq ft About 800 to 1,600 lumens
Typical bedroom 120 to 150 sq ft About 1,200 to 3,000 lumens
Living room 200 sq ft About 2,000 to 4,000 lumens

Is 800 lumens enough?

For a small hall or as fill light, often yes. For a full bedroom, usually no, unless other lamps make up the difference.
