Lighting Calculator LC

Lighting Calculator is the best app to calculate your needs in light bulbs, you will light your home with the exact numbers that you need to use.

For example :-

How many lumens do I need to light a studio 4 meter by 5 meter studio?
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:
lux = lumens × 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.

What is the best lighting for a bedroom?
A bedroom must have different lighting for different uses:

For bedtime use, you will need a lower amount of lumens. A good approximation is 54 lx per square meter.
For reading or other activities, the lighting must be higher. You can use up to 430 lx per square meter.
For specific tasks (sewing, other hobbies), the lighting must rise to almost 540 lx.
This amount of light can be spread over multiple lightbulbs.
