How difficult is it to install recessed lighting?

Follow these procedures:
1. Make sure there is enough room between the kitchen ceiling and the bottom of the roof deck for the recessed fixture to fit.
2. If you are installing the fixture in insulation, make sure you buy and IC rated fixture.
3. Locate all the studs in the ceilings.
4. Mark all of the recessed light locations using thumbtacks located between the studs.
5. Use a template to mark the holes you will cut. If you buy 6″ aperture downlights, then it will be a 6″ diameter hole.
6. Cutting the holes with a keyhole saw, always do the cutting on the upstroke because if you cut as you pull the saw down toward you, you will pull ceiling texture down with it.
7. The lights will come with stud hangers, so when you install them, spread out the hangers and nail them to the joists.

The rest is wiring.
If your ceiling is 10-12 feet, you should space your lights at about 10 feet on center. A good lamp (bulb) to use would be a 100 watt R20 on a dimmer. You may also consider an equivalent 26 watt QuadTube dimmable compact fluorescent.
