Check Out Our Quick Video on Retrofitting Your Fluorescent Light Fixture for LED Tubes



At just 18W, these glare-free, 4 foot DLC LED tube lights use 44% less energy than equivalent luminosity fluorescents and last 66% longer (50,000 hours instead of 30,000), which translates to lower power bills and less frequent lamp replacements. These tubes are DesignLights Consortium® (DLC) qualified and UL listed, qualifying them for rebates from local utilities.

  • 2000 lumens provide light so bright that many business are able to reduce the number of tubes they use, installing two in fixtures that hold four, for additional energy savings
  • For commercial installations, DLC-listed tubes qualify for utility rebates, and UL-listed (E468996) tubes comply with Underwriters Laboratories' safety standards.
  • Instant-on with no flickering or dimness
  • Silent operation—no ballast buzz 
  • 50,000-hour average operating life reduces the frequency of tube replacement
  • Choose a frosted lens for a conventional appearance or clear for a fashionable, high-tech look 
  • Fits existing T8 or T12 fixtures with tombstone sockets 
  • Easy installation—simply rewire your fixture to bypass the ballast and pop in the LED tube (Click for install instructions)
  • Electronic ballast fixtures require unshunted lampholders, see accessories above.
  • 5-year warranty

Review by Richard G

I ordered 35 more of your 4 foot direct 120v lights for a semi-garage. The customer was very,very, satisfied with your product. It looks amazing. The LED soft white lights were 50 to 75 percent brighter than the fluorescents which were in there before. He is so satisfied I am going to do his other building.. The comic book store that I had done previously also called to have me do more lighting at their business also. I am very satisfied with your product and will be a loyal customer.

Thank you for a quality product. (Posted on 10/11/2016)

Review by Lisa Eyrolles

I placed an order about a week or more ago and just received it. I like them so well in my office that I want to replace all of them. I will be ordering more. (Posted on 9/30/2016)

Review by Doug Westmoreland

Really excited about the conversion from florescent to LED. we did our shop with 8 ' LED's last year and just did our main office with 4'ers this month. Much brighter and didn't have to change the fixtures. (Posted on 9/30/2016)

Review by Jon D smith

Very easy to wire, instant on, no more ballasts or fragile florescent tubes to deal with.
Best lighting that we've had in the laundry room out of the numerous types of fluorescents that preceded this lights.
Prompt order processing, no issues with delivery.
Will be ordering 12 more to convert garage and closet lights.

Review by Mark Nelson

My maintenance guy informed me that we were having problems locating 8-foot T12’s to buy for use in these fixtures found in various spaces of the museum. Because of this, we were experiencing dark, dingy, poorly illuminated space. I saw no reason to keep using T12 bulbs, or even 8-footers, since LED’s are readily available and 4-foot bulbs are easier to store and manipulate. My maintenance guy shopped online and found the ELEDLights website with products that met local standards. Our power company would pay for 1/3 of the cost of the project, so we switched from 8-foot T12 to 4-foot LED. ELEDLights sent the lights and fixtures right out and they were easy for my team to install. The quality of light in those formerly dingy spaces is truly brilliant. The users of the space are quite pleased. (Posted on 9/20/2016)

Review by Kevin D. - Murrieta, CA

“Retrofitted my inexpensive shop light fixtures in my garage with the 48" T-8 bulbs. They’re cutting the power consumption by 50% - plus the quality of light is better than before!” (Posted on 11/30/2015)

Review by Bud Herod

I meant to write to you sooner, but being retired I seem to be too busy all the time. Anyway, here in Northern Illinois and Southern Wisconsin your LED tube lights are a definite hit ! ! I just received my order of eight T818W tubes for my garage so I have to get busy and start modifying my fixtures. My first order of four that got bought right out of my hands by the guys up in Wisconsin have them hooked so well that they set up their own account with you for their first order of 12 T8 18W for the aircraft paint room in their hangar and they have me busy modifying all their fixtures as well. Great product, fantastic amount of light, and the CW 5000K light really makes the sprayed parts pop. The old fluorescent tubes made everything look slightly yellow. Thanks again, and I am

Review by Robert J Walt

Just received the bulbs today and had just about all the ballasts removed from fixture. I want to thank you for the great shipping and they all arrived without any damage! SUPER

I also am very impressed with the lights my goodness, I had no idea the brightness and white light, glad I went with the frosted, very nice product at a reasonable cost.

Thanks for sending the diagram for the ballast removal. WENT VERY WELL!

Just wanted to let you know how much I enjoy the LED lights already.
