PARMIDA 20-Pack LED T8 Hybrid Type A+B Light Tube, 4FT, 18W (40W Replacement), Clear Cover, Single-End OR Dual-End Powered, 5000K (Day Light), 2200lm, Works with/Without Ballast, UL

My fluorescent fixtures were driving me nuts. A mixture of bulbs working one day but not next. With my replacement supply being depleted it was time to make a decision. I guess I got lucky. Wanted to replace the T832 bulbs with these. The fixture(s) I have are Lithonia LB432 120 ¼ four fixture lights which have a cover diffuser hence the clear replacement bulbs. Electronic ballast Accupro AC-RC-432IP-120-1. Fixtures were purchased in 2009, so 13 years old. Ballast was not on the approved list by Parmida. In fact, no Accupro ballast was listed as compatible so I figured I would likely have to do ballast bypass. Hoping for the best I just did a direct bulb install. Ha! Works with no issues.So as replacements for the T832 fluorescent bulbs these are really nice. They provide more light than the old bulbs. My only minor gripe is I had to purchase 20 when I needed 12 but now I have replacements which should last many years. The box was delivered with one end torn open but no bulbs were broken. My conclusion on this product is that I would recommend these as replacements. You do want diffuser covers over these. Your mileage may vary but I am very satisfied with this product.

My balast were not compatable for a type "A" ,but cutting them out to convcert was very easy and the light was much brighter than the old fluorescent tubes. In my 4 tube setup I will only use two of the LEDsto tone it down.

I converted three florescent fixtures to the LED because I was unhappy with replacing florescent bulbs and shirt they lasted. Additionally, the ballast fixtures are a huge waste of energy. Bought this pack for 4 dollars per bulb, and they'll last longer than I plan to live in this house. They also cut the electrical usage by more than half. I bought the 5000k for a garage, and now it seems like the space is brighter than the sun. I also used them in my kitchen. It made it brighter than I wanted, but that's better than inadequate light. The install was easy; I'd you have a basic understanding of wiring diagrams it's a snap. I did the ballast bypass because those were worthless. All in all, it's a prlurchase that was well worth it. I didn't need 20 bulbs, but for the cost I was ok with it. I'd recommend 4500k for a garage, but for a kitchen 3500k is probably more than enough. Like I said, 5000k is really bright. But I'm happy with thr savings and the amount of light produced, and at a savings.

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.

I've been thinking of replacing my fluorescent fixtures in my shop for some time now, but gosh! What a chore !?!? Then, I did a search and read an article and watched a video about THESE specific bulbs. This brand comes highly recommended and they came in at a good price. I was pleasantly surprised that I could remove my old 4 ft T12 fluorescent bulbs (Yes, those big fat T12's) and simply take THESE bulbs, plug them in with a quick twist and Wham!!! 💡 Light. No changing fixtures, no changing tombstones (those little white things that hold a fluorescent tube in place), just plug them in. Just to make it clear, "Yes, these special "hybrid A + B" T8 bulbs will fit your old 4 ft. T12 fixture. If the ballast is NIT compatible, you may need to clip a few wires and do a quick bypass, but in most cases, you just "plug & play". There are videos that feature the simple bypass procedure on YOUTUBE but I did not have to do this for fixtures. Old T12 fuxtures.

I was a bit skeptical when I bought this, but it turned out to be exactly as advertised! My ballast wasn’t on the compatible list, but I took a chance and it worked! I read in another review that just because it’s not on the compatible list doesn’t mean it won’t work, it just means that specific brand hasn’t been tested yet. Replaced 6 fixtures (2 tubes each) and noticed that 2 of the fixtures didn’t work. I discovered that it was because of ballasts that have gone bad. So I followed the directions on removing the ballast and doing a direct wire (it really does only take 5-10 minutes to do) and it worked! The one thing I noticed right away was that the hard wired was much brighter than the ones where I left the ballast on. I ended up rewiring (removing the ballasts) the rest of the fixtures and it is really bright! Very happy with the purchase and with the modifications. Bonus: removing the ballast saves even more energy on top of the led savings while being brighter!

Most claim they work with or without the ballast- then you find they have hidden disclaimer like: “install a 1amp inline fuse”, “only work with tombstone ends(connectors)”, etc.This product is as advertised.If I had a complaint:On my first purchase, I was only allowed to buy 1 box at a time. I wish there was a way around that. I manage a building that takes up an entire city block- have old school fluorescent tube lights and would convert all to these. Would save lots of money. If I can find a box of 100ct, I’d purchase 5-10 boxes, seriously.Great product so far.

We are very happy so far with these bulb. We found 1 bulb, in a case of 20, that is not working well. It flickers when it is on, however overall they great.

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.

Early installation. I had old ballasts but the instructions were clear how to modify the wiring to bypass the ballasts. They can be installed directly with changing any wiring of newer ballasts.Had installed few tubes a few months ago and they are working without any problem.

C'est pour le remplacement de 24 néons dans un atelier de mécanique pour l'instant j'ai seulement changer 2 tubes pour voir et apprécier la différence je songe a recommander une autre boite de 20 très satisfait de la qualité de fabrication et de luminosité je le recommande a mes amis et collègues de travail

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!
