We put about 15 of these throughout our house, easy to install and bright.The lights wire and install very well. Unfortunately one of the lights broke during installation. One of he cast aluminum arms that hold the springs and retainers broke while bending the retainer up to install in the ceiling.My rating will go to 5 if the broken product is replaced.Love the lighting for tight spacesVery good product and easy to install thanksI have a few QPLUS 4 in my home. Very bright, easy to install and at a great price too. Its dimming option is a big plus.Easy to install, everything needed was there. Ordered again. Love it.great price and qualityColor too brightNeeded a warmer colorBut very good otherwiseBuild of these lights are very good and look sturdy. Installation was a breeze the wire connectors make installation process smooth however just to be sure I also used electrical tape. Like the fact that you can select different kevlin range to suit your taste. As some have mentioned there is a slight delay when using these lights with a dimmer but not a deal breaker.better and cheaper. this technology is going to kill traditional pot lights at $10 a light these are about 1/3 the cost of traditional pot lights which i have installed in another room. they fit better ,easier to in stall have color changing capability which we love. don't hesitate you won't be disappointedAcheter pour Remplacer anciennes lumières , luminosité adaptée avec gradateur, très facile à installer surtout avec les boîtiers mincesNice but keep changing spectrum colour when you don’t want them too. Better if yo can change the spectrum via a switch on the driver
