NYLL 2 ft T8 G13 Type A Plug & Play LED Tube, Cool White (4100K) Direct Replacement for 17W/20W F17T8, F24T8, F20T12/841 (Without Rewiring or Modification) Ballast Required!

These work. Just replace the old tubes you have with these. Nice and bright, correct color temperature, and easy. They stay nice and cool. No rewiring required. Read the instructions. You gotta have a ballast.

Bought to replace a burned out Philips F20T12 bulb in the closet. I really wanted to swap to LED but without having to do any wiring. This bulb delivers! Super easy to just twist in. The diameter of the bulb seems smaller than the old one, but caused no issues. Length correct, pins slid right in. Turned it on in under 30 seconds, super pleased! I also believe it's brighter than the old bulb (which may have been dimming at its age). But apples to apples it puts off more light for sure. This is the cool white color (same as my old bulb).

I chose the daylight for the replacement. Installation was just like a bulb change. didn't have to change anything in the fixture. I would recommend a lower light rate as they are bright bright just like daylight.

Easy although somewhat expensive replacement. 4000k is bright blue light, 2700 k is warmer toward red. 3000 k bulbs weren’t available, they would be good for a kitchen.

This was a great drop in replacement for my fluorescent light. No more delay when turning on. Great buy!

I should have returned the bulb but I was determined to install it. First thing--the bulb was actually "warped" slightly, like a crooked board. Rolling it on my table you could see a very slight bend in the tube. So that, OR the pins on each end were possibly too long, that caused me about a 1/2 hr of frustration but I finally got the bulb in. It did turn on but I was really disappointed in 4100 Kelvin brightness too. I was replacing a 2700 Kelvin LED lamp and I wanted more light in my tank, but the difference was hardly noticeable. PS. The 2700 K bulb EASILY slipped in and out of my light fixture, so there was something wrong with the new 4100 K bulb. I fought hard getting it in the fixture and didn't want the hassle of NOW trying to get it out for a return.

Loud electric pop when it fried. Smells bad. Not worth the cost if I can only get two years use. Going to another brand. Though probably same poor oversea quality. Light was bright when it worked, so extra star.

I didn't want to go to the trouble of removing my old CFL tube fixture and wire in a new fixture, and I didn't want to remove the ballasts and stuff from my existing CFL fixture in order to add one of the more common LED tube fixtures, so I tried this Plug n Play LED tube and it works great! I just took the old CFL tube out and put this one in and it worked! Took all of 30 seconds. It's only been in use a couple of weeks but it is working great so far!
