I have never installed a lamp or done much electrical work around the house. I'd rather leave that to the professionals.

Mine has moved to the attic which makes life easier. A few tips for those who do household chores. The hole saw you can get requires a mandrel. You can also buy it if you don't already have it. Buy a cheap 2x2 piece of drywall from a big store. Practice cutting holes until you can cut the ceiling.

Make sure you buy a dimmer rated for LEDs.
