SHINESTAR 24-Pack T8 LED Bulbs 4-Foot, 18W 2200LM 5000K Daylight, T10 T12 LED Fluorescent Tube Replacement, Ballast Bypass Type B, Dual-end, Clear Cover, 2 pin G13 Base

Plenty of bright light and haven't had any failures. I always recommend go ballast free on replacement and easy to follow instructions on removing existing ballasts. I'd buy again.

These work great! Perfect bright white 5K light. I went from 4 florescent tubes in my fixture to using 2 just of the lamp positions with these leds and they were brighter than the 4 old bulbs.Very easy to install but if your not an electrician you will need an ohm meter to check the wiring to the connectors.Didn't need a diffuseer as it already had a diff-user screen in the fixture.Gad I bought these LED lamps when I opened up the fixture all 4 of the old bulbs were pretty burned on there ends. Should save some $$ on my electric bill to No More Dual hungry Ballast!!

I have 6 - 4' 4-bulb overhead ballast light fixtures that I was converting to led. I have to use an 8' step ladder to reach. I bought 24 of these led bulbs. I had 4 of the light fixtures completed and they were looking great. I started on the 5th fixture and completed the wiring. I installed the bulbs and only 3 lights came on. Thinking it could be the tombstones, I tried a different bulb, and it worked. I installed the last 4 bulbs and they worked. Only one bulb out of the 24, I thought, oh well, Amazon will send a replacement.I called Amazon hoping to have a new bulb sent to replace the one bulb that did not work. I was told I would have to ship all bulbs back in order to correct the one damaged bulb. I told the nice lady on the phone; you have to be kidding me! She stated, No sir, I am sorry. After we hung up and I was bewildered, and before I left my computer, I received this e-mail below.If you'd like to return the item you may, provided that you're responsible for all costs associated withreturning it to the U.S. (I live in Florida?) You can find Amazon's return address and view a returnmailing label via our Online Returns Center:The young lady on the phone was very nice, but this is unacceptable. The 23 lights in my shop look great, just one bulb missing.If you need more than one bulb, I would not buy from this seller!

Save energy and money!!! My business utility bill dropped by $87. They are so much brighter than fluorescent bulbs. Customers walk n the door and even comment on it. Switching the fixtures to be able to use them was a bit challenging at first. It involves a bit of wire work to remove the ballast. So simple. Just search for a YouTube video. once I figured it out, it was easy.. they work and fit just like a fluorescent bulb.. i have 27 drop ceiling fixtures in my salon. Gone are the days of dull slow to die fluorescent bulbs and me getting on a tall ladder constantly to change them!

Installed 24 of these recently in my existing housing lights that had fluorescent bulbs and ballast. I removed the bulbs and ballast, wired the tombstones direct, and installed these. Works amazing, very bright. Shipping packaging was top notch, best packaging I have seen yet. Highly recommend this product.

Easy install. Happy I was able to remove the ballasts and use line voltage. I'm satisfied with 1 LED tube for every 2 fluorescents I removed in my basement. Originally had 4 fluorescents per fixture in kitchen, but now only running 2 per fixture. Still crazy bright! And I have no worries about leaving them on since they're LED. Plenty of light output, wide angle. Had an issue with 2 tubes (1 wouldn't power on and 1 flickers occasionally) Seller took care of me.I like the plastic covering, so no worries about broken glass tubes from mishandling.Update 10/7/22:I've had about 4 tubes total that I've had to replace which I don't think is too bad since first installing them. A few have a single flickering chip but nothing that is distracting. I've even turned several of the tubes to face upwards so it's not so bright.Update 7/8/2024:I've used the last replacement bulb I had today. I run 24 tubes between my kitchen and basement (1 pack) and I had a handful that were D.O.A. when I first purchased where the seller sent me a replacement pack at a discount. I can't remember if that pack had a few dead ones too, but if assuming it did, I'm guessing I've replaced 20 tubes in a matter of 4 yrs (?)

great

Burt out bulbs in the garage...thee last 45 years!
