Best LED Downlight you can buy!
By Jeff Ainscough
I spent several hours researching replacement downlights before finding these. I bought 20 of them and they are exactly what I was looking for: 4000k, near 1000 lumen, 90+ CRI. I wasn't expecting them to also address the R9 value. These provide great light. Much better than 2700k, 900 lumen CFL's or 2700k, 1245 lumen LED's. See photos. The Hyperikon lights are apparent.

Buzzing With Dimmers Designed for LEDs
UPDATE: Added a star because their customer support is awesome! I called in to get help and they were very willing to find a solution to remedy my buzz problem. This seems to be a solid company and I regret that I can't make it work this time around!
I'm currently finishing my basement and I installed 12 of these on two different light circuits (8 and 4). I have 8ft ceilings, and spaced them approximately three feet off the wall and four feet apart.
I used Lutron LED/CFL three way dimmer switches specifically designed for LED lights like these. You can find the product I used here: Lutron MACL-153M-RHW-WH Maestro 150-Watt Multi-Location CFL/LED Digital Dimmer Kit
Every single light that I installed had a definite buzz - some louder than others but all very noticeable. With 8ft ceilings the room essentially hums when the lights are on. Both circuits sounded exactly the same. I had a few other other dimmable recessed LEDs from a different manufacturer that I tested to ensure it wasn't just the switches, and they did not buzz at all. I have since read through all the reviews on this product and others have reported buzzing while dimming as well. I'm sad to say that I have to send all of these back and look for another manufacturer to give me 4000k LEDs.
It's a shame because other than the sound they are perfect. They appear to be of high quality and consistency, and the light they put off is beautiful. I imagine that if you are not planning on dimming these they are an inexpensive way to upgrade to high efficiency LED. I also highly recommend 4000k in a basement. It is white enough to compensate for being underground, but not overbearing like 5000k can be.

Nice lights but produce huge radio interference.
By John F. Bundy
Nice-looking, bright lights, BUT, be warned, they produce a huge amount of radio interference [RF or EMI] – more than any LED I have ever installed. They are obviously not FCC compliant, and simply can't be used in the same room with an FM radio or receiver. I now know to look for the FC imprint indicating FCC CFR 47 compliance. Pity that, for otherwise they are nice lights.
