Frequently Asked Questions
A can light, also known as a recessed light or downlight, is a light fixture installed into a hollow opening in a ceiling. It provides ambient or task lighting.
The calculator uses two methods: one based on desired footcandles (total lumens needed = footcandles × area) and one based on spacing (number of cans that fit in the grid). The final result is the larger of the two to ensure adequate lighting.
A footcandle is a unit of illuminance equal to one lumen per square foot. It measures how bright a light appears on a surface.
