What is the rule of thumb for recessed lighting? A good rule of thumb is to divide the distance between ceiling and surface by two to give you the maximum distance between fixtures. For example, lights in an eight-foot ceiling should be spaced about four feet apart.
How do you determine the number of recessed lights needed in a room? Formula: total sq. footage x 1.5 = total wattage needed. Total wattage divided by 60 watts (or whichever wattage you select) = total amount of recessed can lights. Example: 240 square foot room x 1.5 = 360 divided by 60 (the bulb wattage I’d like to use) = 6 recessed lights needed.
How do you choose between 4 and 6 recessed lights? To choose between 4-inch vs 6-inch lights for a room, first determine which lighting layers the room needs; General, Task, and/or Accent lighting. Then plan each layer separately. Since all rooms need general lighting, I like to start with that first.
What is the best wattage for recessed lighting? Most recessed lights use a BR30 65-watt light bulb. On average, these light bulbs produce about 600 Lumens. So when looking for a LED equivalent, look for one that has a light output of 600 or more.
