First off, I am an electrical contractor. I think these lights are great besides the fact that these cannot be dimmed!! I have also tried other 12vdc power supplies and they do not work with these particular type of LEDs that are inside. They are about 1/2" thick and most all ceiling drywall is 1/2"-5/8" thick so that means you can just cut the hole and go, regardless of where a truss or floor joist sits. And not having to lay out your can lights according to where the truss/joists are is a HUGE time saver.
They provide an evenly distributed light and these suckers are BRIGHT! I have used many of these as well as the 6" version (which is not as bright) but the 6" ones are bright as well. They have a 120 degree beam angle so you have a wide light coverage. If you are planning on installing these in a large room and need adequate brightness, I would suggest using the 8" ones instead of the 6" version. The outer bezel is silverish/gray color (similar to stainless steel) but I suspect they could be scratched up lightly with some fine grit sandpaper and painted the same color as the ceiling, but I ahve not tried that yet.
One bit of very helpful installation advice.....The power supply that comes with these have an output 12v connector that plugs directly in to a pigtail that comes out of the back of the LED light, and the 120v input on the power supply has a brown wire (HOT) and a blue wire (NEUTRAL) which is a European/Asian color configuration; different from the US black/white wiring colors for 120v but does the same thing (electricity is colorblind). You MUST install these in a junction box of some sort and use the appropriate cover for said box in order to be both SAFE and meet the guidlines of the National Electrical Code. You cannot splice your wires coming from your switch or your existing light on to the power supply input wires without being secured in a junction box. Otherwise you would have a couple wire nuts tying together loose wires just floating in your attic or ceiling space, which is not good.
I like these so much that I am recommending these to any customer of mine that wishes to install recessed lighting somewhere. I just wish that they were DIMMABLE and I would have given them all the stars I could. These lights are VERY easy to install and I probably made it sound more complicated than they really are as far as installation goes. These are about the easiest lights to install from scratch even if you are the average homeowner and not an electrician. I highly recommend these!!!I used this along with a 6" in a bathroom by cutting a hole in the dropped ceiling. Easily installed and brighter than I expected.
