How many recessed lights do you need per square foot?

Measure your room to see how many fixtures you will need. A common rule of thumb is that you use one recessed light for every 4 to 6 square feet of ceiling space. Doing so provides even, overall illumination.

How far should 6 inch recessed lights be?

If a 6-inch light has a spacing criteria of 1.5 and the ceiling height is 8 feet, the maximum space between each light should be 12 feet. This formula is critical for lighting a space because if the lights are too far apart, they will look like spotlights with big shadows between each other.
