Huge improvement over the old fluorescent lights with a bad ballast (was taking forever to come on). Tools needed:1. Both phillips and flathead screwdrivers (or electric screwdriver with both bits).2. Possibly a wrench set or a c wrench. There was a small nut that I had to remove to take the ballast off.3. Wire cutter (some pliers will have a wire cutter built-in).4. Wire stripper (I used a sharp pair of household scissors).5. Wire caps. I used 22-10 gauge ones as you will be connecting up to 5 wires. Wago connectors will work, too.For each bulb, take the wires from one tombstone and connect/twist it with the black wire and the wires from the other tombstone and twist it with the white wire. Doesn't matter which tombstone is connected to the black or white.Generally very happy with the results! Great lighting for our laundry room. I just wish there was a pack of 2 for sale as 4 would be overkill (seeing how long these bulbs are supposed to last).

Easy install and really added much light in a dreary basement. No more waiting for flickering lights to turn on or possibly not turn on.

I’m a building technician for a big commerical company I bought these bulbs cause they were a good deal . Well come to find out they are junk don’t buy all they do is flicker non stop I thought maybe they just need to warm up nope 5 mins later they are still flickering

Wow, have been looking to replace the main lighting fixture in our kitchen for awhile as especially in the winter, the 40 watt (U-shaped) fluorescent's just did not seem to give off enough light. Instead of replacing the fixture with a new LED one, you can simply convert the old fixture to accommodate LED bulbs for less than half the cost of a new fixture. Took me about 10 minutes to remove the old ballast and rewire after watching a you-tube video. Highly recommend, very bright now, is instant on, and should save a significant amount of electricity as the light is usually on 8-12 hours per day.

The color temperature of these are good, but its a bit more white than I expected. Also, due to the the form factor, the light distribution isn't as good as the U-Shaped fluorescent ones. Super easy to install and a lot more efficient. I recommend these for switching to LED, would like to see more color temp options and maybe adjustable color temp.

Not plug and play

I really like the brightness and it was a pretty easy retrofit. I could have used a drawing that showed a dual tube application and since this is a common install, I took one star off for not having a dual drawing. Not hard to figure out though and the rest of the install was easy as pie. I would have liked a 'heads up' on the fact that the tube clips would be a bit large so I could have had other smaller ones on hand. Nice lights!

Installed lamps last week, one lamp was blinking to begin with,I was ok only needed 8. This week two more are blinking, Not good. 3 out of 10 bad so far. They are not flickering, They are blinking
