Bought 1 box of 8 inches and 1 box of 6 inches for our renovation. I love these lights! This was a DIY project that we did with a lot of help from two wonderful neighbors who were our commercial electricians and both were very impressed with this product. They are very thin and could probably fit under the floor joists if needed, we shouldn't have but thought we could so we researched the situation. Also the daylight is very bright. Which I like. We put a dimmer, not ready yet.
