Rated 5.0 out of 5.0 Used with the "correct" dimmer, they are great!
I recently installed these in (2) rooms I just renovated in my home, like others I ran into the humming issue while using dimmers.
I tried using all the suggested dimmers with no success, buying $180 in dimmers to try all the options at the local store. I settled on hours of research finally finding one suggestion through some review of the fixture.
The model that does work with with this fixture without humming on any range of illumination level is the Lutron DVELV-300PH-WH ($74.99 a piece)Yikes. I know this model to work on currently (2) separate rooms with (4) lights a piece.
With the exception of having to use a 75 dollar dimmer, hours of research, I am completely satisfied with these

Rated 5.0 out of 5.0 by Guenther93 Love them - basement project - 40 lights - several dimmers - NO HUM
Last year I finished my basement myself and when it came to lighting I went back and forth between installing traditional cans or simply putting in 4" junction boxes and using the T67 lights. I purchased a few of the lights to check for brightness and color - I purchased trial dimmers to verify that there was no hum as several reviewers claimed. Unlike others I actually followed the instructions about getting an ELV dimmer..
In the end I ended up wiring my entire basement project with these disk lights. All in all I have 8 circuits across a variety of rooms/zones with 9, 6, 8, 6, 2, 2, 3 and 4 of these on dimmer switches. I am using the Skylark Contour CTELV-303PR-WH dimmer switch in 5 of the zones.
The lights are instant on - no lag at all - the brightness is great - much better than the normal 65 watt cans I have. The light warm and very easy on the eyes - it is very hard for me to tell the difference between the normal 65 watt bulb in terms of color - yet the brightness is better.
I have repeatedly read about the hum - but when reading it was clear that you have to use a very specific type of dimmer like the one I described above. If you don't you will get a hum - if you do get the right dimmer switch type - there is ABSOLUTELY NO HUM IF YOU GET THE RIGHT DIMMER SWITCHES. I have put my ear right next to the units with and without dimmers - there is nothing audible either at full power or dimmed. The proper dimmer switch is more expensive - but so are these lights - you are buying them to never have to touch them for 15+ years.
Unlike traditional bulbs - the dimmer does not let you go from 1%-100% range. Generally you get about 40% brightness to 100%. Certainly enough to set a change in mood - but not candlelit. Overall I am happy with the range on dimming that they have.
Installation - I was installing them directly into the 4" junction box. They are designed to be a tight fit. The hardware is pretty easy - they actually come with a dongle that you can hook into your wiring first and then pug the light in - so you can get the real electrical work done without the light. To install you need to pop off the plastic lens to, slide the light up into the junction box, and install 2 screws. Depending on how flush your junction box is to the drywall the screws they provide may not be long enough. In about 20% of the lights I installed the box was inset just a 1/8th of an inch too far for the screw to catch properly. I went to the hardware store and got a box of screws that were 1/4 inch longer and the problem was solved. Screw the baffle flush to the ceiling - pop on a couple white stickers so that the dark screw head covers do not show through the lens, pop the lens on and you are done. NOTE: The light seemingly gets brighter when you put on the lens as it diffuses the light out in more directions.
I spent a lot of time deciding how to wire my basement because of these - and in the end the time saved by simply nailing up junction boxes vs installing cans was huge. Additionally the cost savings on not needing to buy cans, baffles, and lower watt LEDs helped offset the cost of the T67s. Now that my basement has been finished for 1/2 of year I can say I remain very pleased by my decision to go with this product.
Simply put I love these lights and highly recommend them and wanted to offer this review as a counter to those complaining about the hum because they didn't do the research to know what type of switch they were supposed to use. I am likely going to be slowing retrofitting my existing recessed cans with these as I am tired of constantly replacing light bulbs.

Rated 5.0 out of 5.0 by ArminRussi Great Light for low wood panel ceiling
I remodeled the basement and used 26 of this lights. That's a lot of money up front. I staggered them every 6 feet or so.
They work great. I did not use a dimmer. I like the low energy use. One of them quit after about a month of use. I tried to contact the manufacturer but they did not respond. I was able to get a replacement from H.D. I think this is the way to go in the future. Just a 4" can on the ceiling. I hope they get cheaper in the future.

Rated 3.0 out of 5.0 by r5portals Needed as alternative to can lights, but not ready yet.
I am an installing contractor, disappointed that T91 lights were suddenly discontinued, to be replaced by T67. If the move were good for consumers, I would say so. I am disappointed with the 2700°K color temperature of the T67, finding it yellows my paint colors. I wish the choice had been 3000°K as in T91, or that CREE might have applied a mix of phosphors to give a more-full light spectrum.
My strongest disappointment with the T67s I have tried, is in an irksome hum of the luminaire while powered through dimmers. I find the same hum with two dimmers I have tried so far, a Cooper Wiring Devices D106P, and a Home Depot store-recommended Lutron Maestro.

Rated 5.0 out of 5.0 by RJenkins Nice looking light
I purchased one of these to replace the 50 watt par20 halogen bulb above a shower and am delighted with the results.
It uses 1/4 the electricity and produces nearly 20% more light (660 vs 550 lumens) with a nice, broad spread. Color of the light is nice and cool and renders the color of the tile in the shower nicely.
Installed in an existing 5 inch can without issues - the package says that it will fit "many" 5 inch cans. I can't see it being a problem in any as the module is shallow and the retaining prongs are quite flexible.
This one was a little trickier to install than other LED modules I've used as it has a ground wire that needs to be clipped to the can housing that the others didn't have. Just an extra step - not technically challenging.
What is great about these is that they can be installed in a standard octagonal junction box - no need for a recessed can! Properly sealed, a J-box is a lot easier to insulate properly in an attic than a can. There is an included adapter plate for use with a square junction box as well.
My install did not include a dimmer. There is another review here that mentions a hum when used with a dimmer and I've read the same elsewhere. Hopefully, the manufacturer can fix this as it is otherwise an excellent product.

Rated 5.0 out of 5.0 by maverick Nice Light - no hum on dimmer
Installed 10 of these lights in my kitchen. Was happy as the install was pretty easy and the lights give off a good natural color.
4 lights were installed on a standard switch, the other 6 were on a 3-way dimmer (Lutron DVCL-153PR). As night came, and things quieted down around the house I noticed the "buzz" or "hum" (as mentioned by other reviewers). Was pretty disappointed and annoyed.
I contacted CREE (the LED manufacturer) to discuss the issue. They provided prompt customer service, and stated I needed to swap my dimmer for an ELV dimmer. I found the Lutron SELV-300P and Lutron SELV-303P (3-way) switches, installed them and they work great. No more buzzing.
All and all a nice product, the only thing they missed was providing better documentation in the packaging to communicate which products are compatible.
Note: you will want a dimmer with these lights as they are very bright when on full.

Rated 4.0 out of 5.0 by Brhd Great product with a noise?
If this light is hooked to a regular dimmer you will get a noise or hum of the electronics when dimming. That is not normal and it is corrected with the use of a low voltage electronic dimmer. They do run about $60 for the dimmer but well worth it.

Rated 5.0 out of 5.0 Careful with the Dimmer!
As other reviewers have noted using a regular dimmer (even one rated for LEDs) can result in a disappointing, annoying electrical crackling noise as though you are under high-tension wires. I agree with other reviewers that using the expensive ($65-70) Lutron DVELV-300PH-WH dimmer makes all the difference in the world. Now the noise is totally gone and the lights are wonderful.
