How many square feet per can light with 8' ceiling?

 

[Jim Port]

What size fixture, bulb and trim? What is the room? Different rooms require different amounts of light.

Stand size 6" can and bulb it's in living room.

I think I remember reading a 6" can in an 8' ceiling will give an 8' spread on the floor.

Or I could have made this up!

 

[Jim Port]

That is a rough guide.

Also depends on what kind of bulb and wattage you put in....

This is a pic of one part of my garage....I have 16 6" cans in it....500 sq ft...each can has a 23w CFL.

When in doubt...put in more than you think you need....use LED bulbs and connect a dimmer.

I found a formal. Room square footage x 1.5 divided by bulb wattage equals number of bulbs.

I don't use sq footage. I use the dimensions of the room and lay out the lights according to the footprint.
Telling you how many lights is one thing, how to lay them out is another. What if the guide say you need 11 lights, how would you lay them out?

 

[Jim Port]

I found a formal. Room square footage x 1.5 divided by bulb wattage equals number of bulbs.

This so called formula does nothing to account for the difference in lighting levels needed in a kitchen or a family room, work surface height, beam spread from the bulb, surface reflectivity or trim selections. I would consider it almost worthless.

Without knowing the fixture and lamp lumen output and how bright you want the room, there is no way to accurately answer you.:no:

Mfg. should have a cut sheet on lumen and lighting throw.
