About 6,500 lumens. To calculate this result:
Compute the area of the room:
area = 4 m × 5 m = 20 m²
Choose the right amount of lux you need. For a studio, the recommended value is 323 lx.
Find the result using the formula:
lumens = lux × area = 323 lx × 20 m² = 6,460 lm
If you plan to use lightbulbs with an intensity of 1600 lm, you'll need five of them. Read more
