Let me start by saying that the ASD 4 inch LED downlights are very well designed and built and look great on my ceiling. They are very easy to install. Now for the negative part. After installing it in my ceiling I noticed that the lights were not sealed. The part that rotates so you can lead them to a picture shelf etc. I noticed that a lot of dust and insulation got onto my floor through the gap. Also, after installing it, I decided to tone it down a bit. They faded and returned to full light after a few seconds. I tried several times to darken, but without success. Even when muted for a few seconds, they tend to flicker. I don't feel like going back to the attic to strip, pack and send them back to find another set so I decided to just live with them. So finally, if you don't mind a little dust that needs cleaning daily and you don't need dimmable bulbs. It is in order.
