Recessed Lighting Spacing 8 Foot Ceiling - Distance from Wall and between the lights


General Recessed Lighting Spacing
Recessed lighting spacing is an important step when planning recessed lighting. After calculating how many recessed lights you need and settle down on the suitable recessed lighting layout. Now it is the time to correctly space recessed lights to eliminate brighter spots and dark areas. The right recessed lighting spacing enhances the lighting distribution in a room or space and improves the final view of the ceiling.


The Recessed lighting spacing formula is to set an equal distance between recessed lights to get a uniform lighting distribution and make the distance between recessed lights and the wall half the distance between recessed lights. This formula enhances recessed lighting layout design function by providing an even lighting distribution and also improves the lighting layout appearance.

To understand more about recessed lighting spacing you should know the light produced by the recessed light unit take the shape of a cone forming a circle of light that intersect with the surface that is required to be illuminated or the room floor. If you look at that generated light circle you will note that the highest light intensity exists at the center and decreased regularly towards the circle edge. The output light circles from recessed lights should intersect before reaching the surface or the room floor to provide uniform lighting distribution.

Recessed Lighting Spacing Calculations

For general lighting layer to calculate the recessed lighting spacing between the light fixtures for 8 foot ceiling, you should determine how many can lights will be needed and decide a recessed lighting layout then begin recessed lighting spacing calculations by determining:
  • The length of the area to be illuminated.
  • The number of the recessed light fixtures in a single row for that length.
  • Divide the length of the row by the number of lights in that row, you will get the space between the lights.
  • The distance between the wall and the first light unit is the same as the distance between the wall and the last recessed light unit and is half the space between the recessed light fixtures.

Do the same calculations for the width rows
  • The width of the area to be illuminated.
  • The number of the recessed lighting fixtures in a single row for that width.
  • Divide the length of the row by the number of lights in that row, you will get the space between the lights.
  • The distance between the wall and the first light unit is the same as the distance between the wall and the last recessed light unit and is half the space between the recessed light fixtures.
