Armacost Lighting 223412 Purevue 4000K LED Puck Light in a White Finish, Metal, Bright White

Very good quality, solid metal body and very bright. I install into cabinet display with remote control and it works great.

High quality lights. Trim ring is heavy aluminum, which makes a good heat sink to help the little LED chips last much longer. Nice finish, complete and easy to understand installation instructions too.

The ad may say 12V operation but the user manual says 12 or 24V without much change in brightness so there's a regulator inside. That's a beautiful thing for general versatility (and vehicle use) AND these pucks respond to 0-100% PWM dimming at 12V or 24V or anything in-between. And they produce a prodigious amount of nice light. They don't get hot. The beam angle is around 120 degrees so they throw a flood. They might be a little much for the 18 inch under-cabinet duty but for those who like the cone-shaped image on the back splash and plenty of light these are worth a try. Hint: If you see a brand name of three letters, pass on by. As the reviewers say, those get uncomfortably hot.

I bought 4 of the black 2700k puck lights and opted for a flush install. The way the flush mount works is there are 3 rigid metal clips that screw on the top of the unit to hold the light in place from the top of the cabinet. I cut the holes in my cabinet with a 2 1/8" inch hole saw and found that the metal flush mount clips were just too rigid to bend enough to allow the puck light to slide into the hole and to be installed from the inside of the cabinet. I thought maybe I could get it to go if I really pushed hard, punched it, or if I smacked it firmly with a rubber hammer, but I didn't because I figured the light would break or bend. But luckily I had access to the top of the cabinet so I slid the unit in with no clips at first and then screwed the clips from the top outside of the cabinet. That worked perfectly, nice and snug. If you can't get access to the top side of your cabinet to screw the clips in then I HIGHLY RECCOMEND YOU TEST FIT THE FLUSH MOUNT ON A SCRAP SURFACE BEFORE YOU DRILL YOUR CABINET just incase you can't get it to fit either. It would be a disaster to cut the 2 1/8" hole and then switch to the puck mount install method which would only need a very small hole to be drilled for the wire to slide through. As far as quality, not too bad! The flush mount looks really good in my glass door cabinets. At the lowest dimmer settings one of my units is very noticeably dimmer than the other 3 but then matches brightness once I get up to 20% or higher. Also, I'm powering these on the same power supply with an LED strip under the same cabinets. At the highest power settings the LED strip appears to over power the brightness of these puck lights but does balance better at mid power levels. Perhaps if you were pairing these with LED strips you should go with high intensity LED strips only if you need task lighting but then maybe stick with less intensity LED strips if you just need accent lighting, which is my setup. Looking forward to enjoying these!

I recently purchased 6 of the Armacost puck lights and two of their 20 watt transformers. I was tired of using cheaply made lower cost puck lights for my under the cabinet lighting. These are just what I was looking for.It happens that one of the transformers was missing a small piece which helps to hold the wires securely at their connection. I could have easily returned it to Amazon and got a replacement. Even easier though was that I emailed Armacost support at 3:36 pm requesting the missing part. The next morning at 11.37 am I got a reply with the UPS tracking number telling me a new transformer was being shipped to my house. Two days later, I had the transformer! If that's not SUPERB customer service than I don't know what is!This gives me great confidence in this company.Installation was a little harder than I thought because you have to solder or, in some other way use connectors, to connect the lights in parallel. I used the solder method because I thought that would be the most secure. The part that makes this a little hard is that I chose to solder the wires with the pucks installed under the cabinet in order to know where to cut the wires to join them. That meant soldering more than a foot above the counter. It worked out great though!

We waited for years to find the perfect led lights for under our cabinets. Finally we found this solution. They are great lights. Keep in mind that we've had them installed for only 2 days and at this point we are very happy. I'll write another review after a few months. Hope they remain good. We like them.

The media could not be loaded.  I purchased the Armacost PureVue 233412 Dimmable LED Puck, the 810100 10 Watt Standard Power Supply and the 523420 LED Wireless Remote Controller. Very happy with the entire setup! Low cost and easy installation!

Solid and sturdy product. Looks nice and installs easily. However half of the lights are dimmer than the others. It is not a power supply or wiring issue, it is the individual lights themselves. Used an armacost dimmable constant voltage power supply and wired lights in parallel, yet some were dimmer than the others. Unhooked the bright lights to see if they somehow were robbing current from the other lights, but the dim lights just stayed dim. Tried each light individually and found that bright lights were still bright and dim lights were still dim even though no other lights were hooked up to the power supply. Faulty lights themselves. I like the look so it would be nice if they were all uniform in lighting.
