Customer Questions & Answers

How much do they weigh? I need to ensure that my suspension system can support them

Asked by: ss007
They are designed to be installed in grid ceilings, if your grid ceiling is properly installed it should not be an issue. However, at least wherever I have worked the code calls for all lights to be separately supported (i.e. tied to the structure with wire similar to how the grid is supported). The wire is not intended to be holding the fixture exactly in place, it is to ensure if, for example someone working in the ceiling fell and pulled the Tbar the fixtures would not fall to the ground/disconnect from their power cord. Similarly in the event of a fire the fire department can pull the grid down to prevent it falling on top of them.

How do these mount?

Do we have to suspend from wires as my existing fluorescent toffler's do, or can I just drop them into the ceiling grid like a ceiling tile?
Asked by: TerryO
Mounts like regular troffer light in a drop ceiling... just like a ceiling tile.

Can these be suspended from the ceiling?

We have some old T12 fixtures suspended from the ceiling by chains. Can these be done the same way?
Asked by: GoJoeGo
The 2x4 LED Smooth lens lay in Troffer is not designed to be hung by chains.

Have these in a 5000k or full spectrum?

Do you have this in a 5000k or full spectrum? What is the foot candles at 5' away?
Asked by: electriclight
This fixture that you linked for an example is 4000K. I am seeking 5000K. Do you have something that will fit this criteria? If so how many foot candles can I expect at 5' away and can you send me a link?

Rated 4 out of 5 by from The product is very bright, can be wired multiple ways. The product is advertised as dimmable. This is true, but requires a high end dimmer--don't think light switch dimmer type. Several products to dim the lights are available, but in the $58 - 99 dollar range. Requires a 4 wire dimmer, two for power 110 (B&W) and two for the 0-10VDV (Violet and Gray). So , straightforward but not easy or cheap. Two intensities can be reached without a dimmer. Full intensity is Violet and Gray unattached (maximum ohm resistance); minimum intensity by connecting the violet and Gray (minimum ohm resistance) wires. Other than that, the light is good, and 14 that I bought all fired right up after being wired.

Rated 4 out of 5 by from Good Light This troffer was installed in an existing light box over a kitchen island. Troffer dimensions were identical to those of the 4-bulb troffer that it replaced so no modification needed. Placement of the LED lights in the unit resembles a 2-light fluorescent fixture but provides illumination that equals or exceeds the old 4-light unit. Unfortunately, we wanted a troffer that doesn't show a distinct fluorescent bulb pattern when illuminated and were told that there is no such troffer fixture but have since learned that another mfr makes a troffer w/o a distinct bulb pattern so have ordered from HD and will probably replace this unit solely for aesthetics.

Rated 4 out of 5 by from Buskirk Ordered 10 units, all 10 were damaged on the corners, 5 had broken lenses. Was able to use all 10 after bending them back in shape. New lenses are being shipped. Dimmers for these units, 0-10V, are very expensive $70-$100 each and require two more wires to be run to each light and run back to the dimmer. At $75 an hour for an electrician, I chose not to use dimmers, and returned them. Despite it all I love the lights, they look great and give out great light and only use 59 watts. The old fluorescent lights used 160 watts and gave out less light (lumens). Home Depot gave me a 10% refund on the entire order, due to the damage, that was fair. So despite it all you will love these lights! And you will save a ton of money on electricity. I highly recommend these lights, NOT THE SHIPPING FROM UPS!

Rated 1 out of 5 by from poor panels were broken upon arrival when unpack aged and there was no damage to box so came that way from manufacturer had a professional electrician hear and to find out will have to pay for him to come back then tell me it will be another 7-10 business days before i will receive replacement

Rated 4 out of 5 by from Compared with Model # 2GTL4 SWL Only wish the description makes it clear that this light is different from the other one with Model # 2GTL4 SWL, which has a even distribution of LED bulbs across the whole panel. This one with Model # 2GTL4 will appear to have three T8 lamps installed. But, it does give out plenty light!
