How many pot lights do I need in my room?
Likewise, people ask, how many can lights for a 12x12 room?
The typical rule-of-thumb is 24" from each wall, and then 3-5 feet between cans. So in a 12' room you'd probably want two rows of lights. Considering it is a bedroom and you don't need it as bright as a kitchen, you can probably get away with 2 rows of 4 lights for a total of 8.
One may also ask, how many recessed lights do I need for my room?
To determine how far apart to space your recessed lights, divide the height of the ceiling by two. If a room has an 8 foot ceiling, you should space your recessed lights approximately 4 feet apart. If the ceiling is 10 feet, you'll want to put about 5 feet of space in between each fixture.
4 would be sufficient for that space, depending on where you put them.
