Review on QPLUS Airtight Recessed Lighting Downlight by Alex Ferry

They were very easy to install (according to our electrician) - we have installed 16 throughout the house and will be installing more soon. The only problem we had was that they couldn't be rotated left to right. So you need to make sure they line up the way you want them to. Otherwise, you have to rotate the entire block, and the installed block will be difficult to rotate due to the clamps. Also, be sure to mount them far enough away from the wall to ensure good coverage. We used to have track lighting that really brightened the look of our interior. I think we have K4000 - so no daylight and not super warm. perfect for indoor use - and we've put them all on dimmer switches.
