Customer Questions & Answers


do you carry the ivory dimmer switch
Asked by: pat
Well, according to Lithonia's web site this switch does come in ivory....according to Home Depot's web site we can order it in Ivory if we order thru the Pro Desk. This past Monday we went to the local Home Depot an after about an hour of the counter person calling all around...he ordered this switch in Ivory for us....we haven't gotten the switch yet but we are hoping that is what is on order for us.

will this work on the 2x4 fixtures. switch says it's rated for 1200 watts, at 45W per 2x4 fixture that implies 25 fixutes on one dimmer.

Asked by: arthur
The 2x4 LED troffer calls for the same dimmer switch (this is listed on the outside of the box-don't expect the instructions inside the box to help you even a little bit)! I agree with your math and suspect the same switch will work for both size LED fixtures.

How many 2 x 2 troffers can I safety wire to this LED dimmer?

Asked by: Anonymous
I wired three (3) 2 x 2 troffers. You must check the power (wattage) requirement of each troffer to determine the number of fixtures the switch can support.

Does this fit 2x4 led troffer?

Description states only 2x2 but the lithonia 2x4 troffer has wiring for dimmer......
Asked by: mike
This dimmer switch is used for a 0-10V dimming circuit. This works with many of our commercial LED troffers, but ultimately it depends upon your specific model fixture. A driver with a 0-10V dimming circuit will typically have purple and gray leads extending from the driver. You will need to run a low voltage wire to connect these leads to the dimming switch. The only way to know for sure if this is compatible with your fixture is to check the complete model number of your specific fixture and verify the dimming type it uses. Thank You for your question.

Previous products tried failed miserably. Just read the instructions thoroughly as two wires also need to be run to the transformer as well as power to the lights.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from great switch!!! easy to install. you will need to run 2 more wires to the troffer for it to work properly. works great and dims the light to the kind of light that comes in through a skylight during a cloudy day.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.
