configuration for recessed lighting in small room


The room is roughly 11 feet x 8 feet. The ceiling is low at 6 feet 6 inches. A desk will sit at one end of the room and a futon will sit at the other. This room will function as a home office and small guest room. What size recessed lighting should I get, how many and where should they be placed/laid out?

Also, heat is a concern since the ceiling is low so anything that puts out the least amount of heat is preferred (not sure if that affects light size and/or layout).

Thanks

I would use four 6" cans with CFL lamps, spaced equally from the walls.

4? Really? I just heard the rule of thumb was 120 watt per 100 square feet. Given that the lights are at least 60 watts each your suggestion would be 240 watt for this 88 feet. Is that overkill?

At 6'6" I wouldn't used recessed cans at all.
Nor any other center of the room sort of ceiling fixture.

Think valance at the ceiling/wall edge... and table/desk/task lamps. LINK

I would toss any "rule" about watts per square feet.

You need to look at the number of lumens that are effectively delivered to the area. A 65 watt flood will put more light where you need it, than a 100 watt A19.

As far as 60 watts per can in your math, R30 bulbs are made as 45 watts and 45 watt equivalents.

Dimmers are also great for controlling the amount of light.

4 cans with lower wattage bulbs and/or dimming will give you a much more even light in the room, than 2 cans with higher power bulbs. That is particularly true with your very low ceiling.

One way I was told, however high your ceiling is, is how much spread you'll get.
6'6" ceiling 6'6" spread of good light on the floor using recessed lighting.

Again thats just what I've heard.

there are exceptions to every 'rule of thumb'
Taller ceiling require more just because of distance to the floor.

I ended up installing two 6 inch 12.5 (65) watts LED recessed lights roughly 32 inches from the wall which made them 5 feet and 6 inches apart. I'll let ya know how well or how poorly the room is lit (still gotta tape, mud, prime, paint and finish up electrical).

Guess I should have said that I would put 4 in, it's easier to install a LED dimmer later, than it is to add more recessed cans

Just my opinion
