I am remodeling a 12x12 kitchen and want to add recess lighting. How many 6 inch led can lights would I need to fill the space with light?
There are a lot of options depending on what the actual layout looks like and what sort of look you want, but you could Follow The Ceiling Height Rule Of Thumb:
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.
