Calculate the number of lumens and fixtures needed for a room. Based on recommended lux levels for different room types.

Area: 20.00 m²
Recommended Lux: 150
Total Lumens Needed: 3,000 lm
Fixtures Needed: 4 (using 800 lm each)
Estimated Power: 40 W (10 W per fixture)

Formula: Total Lumens = Area × Lux. Number of Fixtures = Total Lumens ÷ Lumens per Fixture.

Room Lighting Calculation

Proper lighting design ensures adequate illumination for different activities. Lux is the unit of illuminance (lumens per square meter) .
