How many watts of light do I need per square foot?

An average LED lighting system draws about 32 watts to serve 1 square foot of grow space. The wattage in a grow room could be amplified up to a maximum of 50 watts per square foot. Going beyond that amount would create a too strong indoor plant light intensity, which could stunt the growth of your plants.

How many watts do you need per square foot?

The number of watts = area x 10. This result is valid for houses containing rooms whose ceilings are 8 feet high. In the case of modern homes having higher ceilings than 8 feet, the rule of thumb for the calculation is 1.25 watts per cubic foot.

How do you calculate lighting per square foot?

Multiply your room square footage by the footcandle requirement. For example, a 100-square foot living room, which needs 20 footcandles, will need 2,000 lumens. A 100-square foot dining room, which needs 40 footcandles, will need 4,000 lumens ² (see PDF and complete footcandle index).
