This dimmable LED magnetic strip retrofit kit is designed to replace the ballast and tubes in 2' x 4' fluorescent troffers. Bright and powerful—the 30-watt LED retrofit kit emits 3700 lumens of warm, cool, or natural white light—equivalent to the output of 2 32-watt fluorescent T8 tubes. They're designed to last 5 times longer than fluorescent lights. The LED lights have magnets every 5” for secure mounting, and they operate on 100-277 VAC. A 0-10V dimmable constant-current driver is included, and brightness can be controlled with a 0-10V dimmer. This LED magnetic retrofit kit is perfect for homes, offices, schools, hospitals, and more!

Brilliantly simple solution

The other reviews are right on point.
Retrofit couldn't be easier. Longer wires would be nice, no biggie.
Used the 2 strip (4000k) to replace 4-T8's.
Actual light output is a match. Nice clean white light (no blue).
My picture doesn't show the greenish cast from old existing florescent troffers.
Couldn't be happier. It passed the test. Will replace them all.

Easy and great.

Very bright. I had 4 double 4ft fluorescent lights (8 light total) Replaces them 2 double 30W LED and got more light then I had before.
Installation is very easy, just read manual carefully as it is not very clear from the first read.
The best thing is there is no need to drill holes, attach anything with crews and anchors - everything is hold on magnets.

Awesome product, needs more wire.

I have order well over 100 of these for my company and have found them to be super easy to install. Our average bill is over $100k a month and after installing them for most of the company or bill has dropped by 15%. we have also ordered the 150 watt UFO's and 200 watt UFO's and are continuing to replace all of our High Bays with them. The only thing i would recommend is that they need longer wire on both UFO's and the 4 foot kits. If you gave more wire i do believe it would be better, 2 feet of wire is really short specially on the UFO's

Will buy more

Straight forward easy install. Very bright white light. More light than my expensive full spectrum florescent lights. More than 50% savings in energy. ( 64W vs 30W )
Will buy more to start changing out my 8 footers.
