Who many light intencity in400 sq ft area

Question

Accepted Answer

The number of light intensity in a 400 sq ft area depends on the type of lighting fixtures used and their wattage.

The number of light intensity in a 400 sq ft area can vary based on the type of lighting fixtures (e.g. LED, fluorescent, incandescent) and their wattage.
Calculate the total lumens needed for the space based on the desired lighting level (e.g. 20-50 foot-candles for general office spaces).
Divide the total lumens by the lumens output of the chosen lighting fixtures to determine how many fixtures are needed.
Consider factors like ceiling height, color temperature, and light distribution when determining the number of light fixtures needed.
For example, if using LED fixtures with an output of 5000 lumens each, and aiming for 30 foot-candles in the space, you would need approximately 24 fixtures for a 400 sq ft area.
