How do I determine how much light I will need to properly illuminate a space?


The answer to this question depends on the type of activities for which the space will be used. If it is a space for reading or cooking, you will want more light than if the space is strictly for entertaining. However, this being said, there is a general formula that can be used to determine the proper amount light (expressed in wattage) for a room. This formula is as follows:

Square footage x 1.5 = approximate wattage required

For example, if you are looking to illuminate a 10’ x 10’ space, determine the square footage (10 x 10 = 100) and multiply that number by 1.5. In this case, 100 x 1.5 = 150. Thus, you will need approximately 150 watts to properly illuminate that space.
