Discount T8 LED Tube - PACK OF 2 - A 4ft. (48") Fluorescent Tube Replacement

Customer Ratings:

I purchased a two pack of these. Although packing included plastic bag inside of shipping tube inside of a box inside of another box, there was a dent in the aluminum housing on one bulb and numerous scratches. The bulbs were instant start. Although advertised as cool white, they were labled 5000K and looked quite a bit warmer that some 2044wh bulbs purchased from LED Wholesalers which were advertised as white and were unlabelled as to color. I purchased both to see which I preferred, the item being reviewed was less harsh than the 2044W. So beware that the advertised colors are not standardized. I did not return the dented one yet as the item is out of stock and I really do like its color, bright but not too harsh. Try a few bulbs before making a large purchase. All in all, trying to figure out the color on Amazon and the vendor's websites is difficult and confusing.

My old Fluorescent tubes had started to flicker, though it could have been the ballast. I decided to replace them with LEDs and ended up choosing these based on various reviews. I'm very happy with the increased brightness, the new-found silence and the instant-full-on behavior. The power savings is a bonus, though I'm not sure it'll ever pay back unless it was the ballast that needed replacing. Some of the existing wires in my fixture where too short, so I had to patch in an extra section of wire.

You saw the price already... I think they are worth it. It takes about 5 min to bypass the ballast in the light fixture. YouTube "how to remove fluorescent ballast" and you can watch a video. The instructions that come with the lights are good enough to figure it out, but pictures are nice to. My light setup is negative on one side and positive on the other, the lights work fine. I am not sure about longevity yet because I just installed them. The only thing besides the price that I don't really like is that the lights here are cooler than what was installed. More blue, but I'm sure I will get used to it.

Honest reviews on T8 LED Tube - PACK OF 2 - A 4ft. (48") Fluorescent Tube Replacement

The lights arrived on time and were properly packed. Two problems. Only half one of the two lights came on, that is, only 24" out of the 48" lit up. The other light worked fine (so far). The other problem is that these seem to be about 1/4" shorter than a standard T8 lamp. This makes it very difficult to install in a standard fixture and I had to modify the fixture so it would fit and not fall out. One other reviewer said that his was 1/8" too long. If this is the case, then they have a major problem with quality control. I will have to find out how the seller will replace the defective lamp. Since it was "fulfilled" by Amazon, I guess that I have to deal with the seller directly.

Bright. BRIGHT!!! I replaced a dual-tube setup (40 watts each) and this lights up the room several times brighter. Pretty easy to install, too. Hint: if your fixture has separate ballast wires dedicated to every single pin on your existing fixture sockets, you don't need them: just one wire going to each end will suffice, because the LED driver built into these tubes are connected to both pins. Mine had waayyyy too many wires to connect everything with a wire nut, and then I discovered that most of them are completely superfluous with this LED tube so I just cut off the extras and terminated them with their own wire nuts.

Downside: not dimmable (I tried). In my computer room, having two of these puppies is like being in direct sunlight, probably not the best choice; I may wind up flipping them over (unlike omnidirectional fluorescent tubes, these have distinct "up" and "down" sides, which probably contribute to how vright they are). For a workshop, garage, etc., they are unbeatable. And completely silent, and instant full-on, and low-energy.

And BRIGHT!
