Rated 4.6 out of 5 by 9 reviewers.
Rated 4.0 out of 5.0 by Works well with the TLED trouffer Bought and installed this dimmer to use with the TLED trouffers. Works as expected and installation was standard. Two things for consumers to be aware of that I learned after purchase 1. Any 0-10v DC Dimmer will work with the TLED trouffers (these are dimmers usually used to dim dimmable fluorecent ballasts) I mention this because it is possible to find these for a lower cost than I paid for this dimmer on . 2. You either need to run 4-wire feed wire to the lights or do like I did and run a seperate "control wire". I ran 12-2 MC for power and a seperate 16-2 "control wire " for the low voltage (the dimmer uses these extra wires to dim the lights). Just wanted people to be aware that this dimmer does not work like ones they may be used to in their house. April 10, 2012
Rated 5.0 out of 5.0 by Very expensive, but a nice product I got a Lithonia 2x2 LED Troffer for a basement room I did. It was a perfect choice because of the low clearance and drop ceiling. It was only after trying a cheaper LED dimmer switch (and having the light pulse like crazy) that I realized that I needed this switch (with low voltage gear). I had to run another electric cable to the light to accommodate the additional low voltage wires, so snaking the wall was not a fun experience, but it didn't take long. The price for this switch is very, very high (compared to all other dimmer switches). I doubt it is Home Depot though, rather it is Lithonia driving the price. Overall, I am very happy with the light and switch. They look great and they both work great. I am a little bummed that I had to spend so much money, but practically all home projects cost more than you anticipate. March 10, 2015
Rated 4.0 out of 5.0 by LED TOFFER DIMMER SWITCH I used these dimmer switch on led lightning after I found out that reg, dimmer switch would not work. They came with no wiring diagram, had to call the company that makes them to find out how to wire them. They cost 4 times more money then reg, dimmer switch. Additional 14-2 cable is needed TO THE LED LIGHT for the dimmer to work. January 27, 2015
Rated 4.0 out of 5.0 by LED Dimmer Switch Overall, I am very pleased with the dimmer switch except for one thing. Installation instructions online do not say that the switch must have separate wiring for low density wires which connect each light to another. My technician had to call the manufacturer for instructions. Otherwise, I would recommend this switch to others--it has good appearance and works wonderfully. April 15, 2014
Rated 4.0 out of 5.0 by Works great, looks great, way overpriced (not Home Depots fault) This installs easily and looks good. Way overpriced for what it is, but that's not Home Depots fault. I used it with an LED driver and it worked well. July 30, 2013
Rated 5.0 out of 5.0 by Worked as expected! Did everything we expected, and even a couple of features we didn't expect. Very nice product. January 22, 2013
Rated 5.0 out of 5.0 by so far so good Easy installation. Remember to run 4 wires (plus a ground) to your 0-10V troffer. Two for power and two for the 10 volt dimmer ballast/driver. March 27, 2013
Rated 5.0 out of 5.0 by Simple and does the job, but should be way cheaper If you need to control a fixture with 0-10 V dimming wires (purple and gray) but don't want to buy a full-blown control system, this will do the job. However, it's way too expensive for what it is. This must have incredibly high margins for the manufacturer and/or Home Depot. May 29, 2012
