Great experience, fast shipping, will be ordering again. One end of the shop has been converted to your LED 5000K lights, in the process of switching to your LED lights in the main section of the building - you can see the difference next to old fluorescent bulbs.
Fantastic! I had to check 3 different sources because I didn't believe how easy it was to retrofit. Double the light and no hum. Can't wait to see the savings. Will be ordering another 50.
The LED tube lights are great. I converted three 4 tube fixtures in the basement. And converted these four 2 tube fixtures for my sons garage. They give off plenty of light and the price is a value.
These bulbs are brighter, warmer, and more satisfying than the 40W fluorescent bulbs I replaced. Bypassing the ballasts was more work than I expected but after 5 or 6 of them, it became very easy.
Updated lighting at church went from a 4100k fluorescent 32 watt tubes to the 18 Watt 5,000 k LED tubes. Lighting went from an off color yellowish light to a nice bright crisp clear whiter light.
When we received the bulbs, 7 of the 25 were broken to pieces. We contacted the company & in a matter of a few days & couple correspondences, we had replacement bulbs sent to us!! No flickering, great bulbs for great price. Will order more!!
I bought 4 pack of 25 boxes. One was broken during shipment. HDL gave me " no hassel" refund or credit on my next purchase. I decided to order more and recieved the credit.
The first light panel in the picture shows how much brighter the new LED tubes are versus the old Phillips in the other two panels. The best part is that they use half the wattage than the old tubes. Great product! 👍
One of our most important customers, a manager of a fleet of ocean going ships, came to us for a fluorescent to LED conversion solution aboard their ships where large voltage fluctuations and vibration were a major concern. They had tried other brands of LED tubes with no success. The Greentek Versa tubes have proven to be extremely versatile and reliable in rough environments. Thus far, they are the only LED conversion tube that we have found that will hold up in this tough environment with such ease of installation and no fixture modification required. The light quality of the frosted Versa tubes is exceptional - the attached pictures show a before and after Greentek Versa tube installation. Before the lights created stripes on the floor and were a safety concern, the frosted Versa tubes create a bright even distribution.
Received the tubes today and were installed with ease. Happy to report that there were tube clips in the box.Good Touch. Packaging was good with a Fragile sticker on the box. Overall experience was great and recommend Geen Light Depot for my future needs. The lights that I purchased have a 5 year warranty. Thank you.
Ordering was very easy and quick, I only needed and ordered a quantity of 12 bulbs and that's exactly what I received and delivery was quick. One bulb was broken and one bulb does not work but man do they make a difference in my basement. Not sure what to do about the 2 that I cannot use hopefully this response will get things started. Would differently order these again. So far I've done my 2 car garage and now my basement. Great product at a good price. Thank you.
We used these to replace 14 fluorescent tubes in our wood shop after the ballasts started dying in those. Removing the ballasts is not a big deal if you can strip wires, and these lights are brighter and have better color than our old fluorescent tubes. Now plan on doing some in the garage/ metal shop.
Like that they can work with or without ballast. Easy to rewire after removing ballast. Customers are amazed at how much light they give off compared to fluorescent bulbs. Have purchased several cases and just got another to have on hand.
