PARMIDA 20 Pack UL 4FT LED T8 Hybrid Type A+B Tube Light Bulbs, 18W, 4 Foot Plug & Play or Ballast Bypass, Single OR Double Ended Power, 2200lm, Fluorescent Replacement, Clear Lens, T10 T12-4000K

These are easy to install and very bright. I used them to brighten out covered parking area.

These Parmida LED T8 Type A+B 4ft 18W Light Tubes are spectacular. Brighter than my old florescent tubes and I love the White as sunlight color. My workshop seems to have come alive. Unfortunately, Amazon shipped me what appears to have been bulbs that had been previously installed and to top it off, 5 out of the 20 were broken. Had to return the first case of bulbs and second case appear new and none were broken.

Good product for retrofit jobs.

Thanks to some YouTube videos, I rewired the fluorescent tube fixtures in my garage to LED. It was super easy. These double-ended tubes gave me options as to how I wanted to do the wiring. The tubes work great, are super bright, and were very easy to install.

There are many different brands for sale here on amazon and it feels like Russian Roulette. Read some reviews and decided to try these. I prefer the 4000k color as it appears white to me and gives me a better CRI. This color also fatigues my eyes less here at work. I replaced some Sylvania 4100k octron/eco 32w bulbs that were 6 months old. The color seemed off to me on these and they gave a yellow tinted light. These were rated at 2900 lumen with a CRI of 83. The Parmida were direct plug and play replacements. I did not remove the ballast and just replaced the tubes. They worked with no issues. The lighting in my building is 277v and there are some bad ballast and I will be wiring those direct next week as I test how well these lights work. So far the only issue is the lumen descriptor as it states 2565LM and the box states 2376. To my eyes these led tubes are brighter than the old ones and they are rated at 2900. I will upload pics later if I can. I did not have any bad tubes in the box so far and none were broken as I got the clear glass tubes. I will be ordering more of these for the rest of the building as I need about 200 more. This has been a great product so far.

PARMIDA T8 LED light replacement are simple & Straight forward. I ordered 2 packs (20 tubes each) and do the installation in 2.5 hrs with minimal help of 10 fixtures with 4 tubes. I already ordered 3 more packs to replace the rest and spare.

Really improved the office feel! We can now see in areas that appeared dark with the older bulbs! Just swapped them out, and turned them on!Two were damaged on the way here but I’m sure the seller is sending them now!

I bought these primarily to avoid having to rewire a bunch of various fixtures throughout my basement and garage. Sadly, they did not plug-and-play with any of them. To be fair I didn't confirm ballast model numbers so some of that is on me, but if NONE of the different fixtures I tried worked you might want to keep this in mind.After rewiring one fixture to bypass the ballast I was able to confirm these lights do put out a good bit of light and the color temperature is reasonably pleasant and warm. Unfortunately the lack of any built-in diffusion (like many other LED replacement tubes) makes for a rather harsh light. Furthermore, there is a noticeable delay when turning these on -- like almost a second. All my other fluorescent tubes on the same circuit light almost instantaneously then this one pops on a bit later. Yuck.So these are going back as I see no reason to pay a premium for plug-and-play when they aren't, at least not for me.

This is my second purchase; clear this time and frosted the first time. For performance and price this is a top product. Hopefully a few years from now I'll be able to say durability was top notch too. As you might expect, the clear gives a little more light at the expense of harshness but not too harsh for my workshop. I redeployed the frosted ones from my shop to other areas of my home. Highly recommended.

I purchased 20 Led bulbs -- They came well packaged even though the box was damaged there was no damage to the bulbs. Installation instructions were easy to follow with options. I decided to go the route of removing the ballasts from the fixtures. I replaced 4 bulbs in the basement of the house and 12 in my shop. The improvement in brightness to the shop and basement was excellent.

100% would recommend these bulbs.They are made of glass, emit a very nice colour of white.Using these in our cultural centre and a convenient store. Works awesome!

Does not work with ballast. Had to rewire

Good replacement for florescent lights. May require rewiring.
