8 Pack F8T5/CW Fluorescent Bulbs, T5 12 inch 8 Watts Under Cabinet Light Bulb Cool White, G5 Mini Bi 420 Lumen

Perfect size for a replacement bulb for many of the RV overhead lamps that require 2 bulbs of this shape. There's a trick to removing and installing - holding the bulb on the end, not the glass so you can't cut yourself, gently ROTATE the bulb slightly into or out of the socket. Usually it's just one bulb that went bad - you may have to try them both to determine which one it was, so keep track of which is which. Replace both if you have to, and it's good to keep a spare or two. This is a good start if you're building confidence with your own repairs. 1/2/2026 UPDATE In 3 months I have replaced 2 already in the same lamp. When one bulb goes out, the lamp quits working. You don't know which bulb quit, so you have to test both bulbs with a new bulb. So the questions now is: Is my lamp defective or is it the bulbs don't last long? Sometimes life is just a series of troubleshooting efforts! The Zephyr, Bebe & Lori

Clear, bright, works fine

The lights haven’t out in my dad’s kitchen for the longest time. These came fast and were so easy to install. They are great!

Evidently there is a right and wrong way to insert these bulbs. When i first put one in, it didn't work. After several tries, to make sure I was getting a good connection, i decided to turn it around. After I did that, it worked immediately. Comes with no instructions so if you buy these bulbs, just keep in mind what I just said .

Cheap replacement for a bulb in my old beer light. Easy install works as is should.

Great price Good quality It's perfect

The bulbs are Absolute junk!!! installed 40 of them in my wearehouse and about 4 days later they started failing. Most burnt out and had to replace them with phillips brand. Reached out to distributor/ manufacture and Amazon and nothing came about replacing them. DO NOT BUY THESE YOU WILL REGRET IT. Absolute Chinese junk crap.

They seem to work well. If you have to have fluorescent lights, these are as good as any the packaging in the shipping were great.

Product as described - Arrived promptly! I ordered the 10 pack based on a few reviews (bulbs are bulbs!) Easy to Install : )

Perfect replacement

Las compré para una lámpara que tengo en la cocina, no conseguía por ningún lado este tamaño de focos y estos fueron lo que necesitaba.
