I have one light switch in the kitchen that turns on 4 recessed lights all together. Can I put a dimmer on this switch? Will all four lights dim at the same amount?

Yes, and yes they will all dim together.

Since you only have one switch, you just need to replace it with a dimmer switch. The only thing to look at is the maximum wattage for the switch. Add up the wattage of each bulb (probably 65 each) and then buy a dimmer rated for at least that value. I'd probably get a dimmer with a slightly higher wattage rating.

There should be just two wires on the old switch, and they will just need to be removed from the switch and put on the dimmer. Generally, the dimmer will use small "wire nuts" to attach the wires (instead of screws like the switch has).

In use, note that the switch plate may become warm, but unless it is uncomfortably hot, you should be safe.

Here is a link to the procedure.

Best of luck,

If this switch is part of a multi-gang box, the dimmer looses some of it's rating depending on how how many of the sides of it have to be removed to fit in the box. It's intentional. Full rating with single gang box.

:) Thanks, sounds easy. Should I look for a 600 watt dimmer then?

Yes, unless you have some mega-large bulbs :D
The 600W size is pretty common. And what K.I.S.S. says about derating is important to make note of. You might have to remove one or both sides of the dimmer to fit it into the switchbox if there are more than one switch in there. Check the instruction sheet, but I'm guessing with both sides removed, you'd still be okay with only 4 65W bulbs.

Make sure to turn off the power before proceeding. I've fried dimmers by not heeding this advice--but at least it wasn't ME that was fried.

If CFL's. Be sure they are dimmable.

I have six recessed lights on one swtich over island of my kitchen and another two recessed light on a second swich, over th breakfast area, both controls are next to each other. On the other side of the kitchen, by the back door, I have one switch that controls the six recessed lights, that are over the island, can I put a dimmer switch on these lights?

You can put a 3 way dimmer, in one of the 3 way locations.
You can put a single pole dimmer on a single switch location.
4 60 watt bulbs are 240 watts, 300 watt dimmer should work fine,
It is less work for a 600 watt dimmer.
