Hi All, I have a house that was built in the 1940’s and has drywall throughout. I installed a 6” recessed light in the bathroom a few weeks ago. I ended up drilling some holes and using a fine tooth saw blade to cut the hole. I noticed while cutting slowly a couple times the blade caused the paint to chip in spots around the edge. Think cause there are so many coats on it over the years luckily the trim covered it. Now I want to add a half dozen 4” ones in the kitchen. I am going to purchase a 4” recessed lighting hole saw for this. Am wondering if the hole saw could still cause this issue and any recommendations on how to keep it from happening. Thx

I bought a Cree bulb from Home Depot. The light fixture is from the 60's and the three inside mounting bracket screw heads prevent the bulb from going in. A previous Kobi bulb fit fine but they are out of business. The Cree bulb is 129 mm across while the old bulb is 127 mm. Short of going to a bunch of lighting stores and measuring the bulbs, does anyone know what other brand would fit?
