The product didn't fit, and honestly despite saying it fits 6" HALO, whatever it is. There's no room to hang them inside The case. Also the cartridge isn't attached to anything so the whole bulb is hanging and the bezel/trim is hanging. I first ordered different bulbs than the ones I have now. The lighting in my ceiling is 23 years old old. They could be hooked and the socket needs some support. I literally can't find anything other than white that will fit. I've been looking for PAR 30 for weeks and Revain's description says it will work with PAR 40 bulbs. I am definitely disappointed with myself but god why fool people into saying they fit one size when what Ivered says is meant for another?
