I screwed them directly to the drywall and cut a 1/4" hole for the wires. Two of my lights had structural members above the ceiling so I couldn't align all of my originally planned glass lights. This fixed all the issues. I gave it a 4 star rating. I put them in a chiropractic office and wish I would do a little warmer color. 5k is quite (much) white/ blue.I hope when another office changes it will not be so obvious.I highly recommend this style of light
