LUMINOSUM 4 Inch 9W COB LED Gimbal Downlight with Junction Box, 700lm, 60W Equiv, Dimmable IC Rated Airtight, ETL & Energy Star Listed, Natural White 4000k, 12-Pack

We were able to daisy-chain six of these on a single three-way circuit with absolutely no problem. After about 7 months, one of the lights stopped working. We exchanged lights from one plug to another and have determined that we have one bad adaptor (the 3" x 3" x 1" box that goes above the light) after this brief period of time. Awaiting for the manufacturer to see how they respond to providing a replacement adaptor unit.UPDATE: Interacted with Luminosum when one of the adaptors went bad - they sent a replacement at no charge within a few weeks. Good customer service!!

Easy to install and good lighting

Bought 24, installed 5 so far.Brightness just right.Wish the JBoxes were but bigger but they workable.Fairly priced, hopefully they last.

The design is bulkier than others I’ve bought but that part you don’t see anyway. Just be mindful for clearance issues. Nice and bright. Has a spotlight type of beam so these make for better accent lighting than to light up a room. I have 9 of these in a bedroom and i am pleased. I took the 4K colour was temp and it’s easy on the eyes and my pictures come out well lit. They don’t work well with my wemo dimmer so be mindful of that - they barely dim. These are a good buy but you must overlap the beams or there will be weird shadowing / dead spots so place them accordingly.Update. It's now Father's Day 2021 and I have four dead lights. Sometimes it's the bulb, sometimes it's the ballast that quits. That makes 6 total dead out of the 9 setup because I replaced 2 since the initial purchase. They don't last. Shameful. I have to replace them with a different brand. This brand is the only brand I had to replace and I have leds throughout the house.

Easy installation. Lights have good brightness and color

Easy to install, worked perfectly on my vault ceiling. great light on a dimmer switch

We are still in the process of installing the lights in new construction. The drivers are wired in nicely. It is nice that the lamp modules disconnect from the driver boxes to facilitate the installation.

Haven’t installed yet but excited to see how it’ll come out.
