8 Inch/ 8" Plug & Play T9 Circline LED Lamp - Daylight (6000K) Circular Bulb Directly Relamp & Replace 22 Watt Fluorescent Bulb FC8T9/D (Without rewiring or Modification) - Ballast Required!

This light is an awesome little replacement for the fluorescent bulb. This thing is a direct fit NO REWIRING AROUND THE BALLAST. I just unplugged the old fluorescent bulb and plugged in this LED replacement and fitted it right into the exact bulb holder. Usually when it says direct exact replacement there is still work to do but, not here. This was SIMPLE AND DIRECT. It was a bit expensive so the investment may yet be worth if it lasts a long time. The light is very bright almost too bright but can it really be too bright? It is bright enough I am considering not replacing the 10” bulb next to it. Just for comparison this little jewel is brighter than both of the Fluorescents that came in the original round fixture to begin with. So when I have the money I might just get the bigger one and replace that remaining fluorescent as it is in the kitchen and above the sink. I’m thinking about other places to put another fixture just like it because it will illuminate very very well. The total cost to replace each bulb is just at $30 each so again if it lasts 5-10 years then yes it will be worth it.

They said it was bright but they all say that, well let me tell you this is BRILLIANT not just bright and it’s a great even brightness that seems like sunlight. As an avid modeler who has 64 year old eyes (and everything else) this light is a god send. I used to have a hard time telling the difference between the LEGO colors but not now. I can also see the tiniest little details on my n scale locomotives without wearing my magnifying glasses because of this wonderful light which I installed in my trusty 40 year old Luxo magnifying lamp. It was as simple to install as a replacement fluorescent lamp an worked flawlessly from the start. I was hesitant at first because it seemed expensive but I am so glad I took a chance and bought it, I would now gladly pay twice the price asked for this awesome led replacement light. Thanks NYLL for making this great product right here in the USA!

Excellent.....Also purchased the 12 inch Circline to replace two fluorescent bulbs that had become dim and flickering. What a difference! Light is VERY bright, daylight color, brighter than the fluorescent were when new. In recent years the fluorescent circline have been difficult for me to find locally - and the last ones I purchased were not perfectly round so had some difficulty putting in the fixture. Not these! They fit correctly and the plugs went in easily. No need to rewire the fixture either. Will definitely purchase again. I only wish this company would make a T5 tubes in 24" for my plant stand.

This does a good job of matching the warm 2700K color temp of the other bulbs around my workbench area. Very nice and bright. No flicker.

I bought two of these bulbs for two different magnifying lamps. The are used intermentantly, mostly during the winter months. One died after about 3 years. While that seems like a long time they are rated >50,000hrs which would be almost 6 years of constant use.Light from the bulbs is even, and good color (what I expected from 6000K). Easy to install as they are directy replacement for CF bulb.

if vs original 10yrs old Philips 8T9 tube light, this is brighter a lot. We were using this for industrial magnifier ring light and no need worry about tube clacked anymore with hammer touched and no need worry about broke discharge tube air suck in cannot use it anymore. There was more cheaper LED ring light, but it is required remove ballast and connecting work, LED is connection very directional, so worried work time and do not want company building power down, so if thinking about risk price is even so we purchased easy way on this. I hope another several dollar price down in the future , we buy more. Only noticed people cannot expected exact center as original tube light position, it will off 1/8 inch maximum because that fancy tilting connecter they have. That is good function, makes easy to install.

I purchased 6 each of the 8" and 12" 6000k versions of these lights and all was well for several years. Eventually though, these WILL burn out in a spectacular way. Fortunately I was home when they did and I was able to smell these when they caught on fire and put it out quickly before it spread to the rest of my house. If I had been traveling, not so sure how this would have turned out. I strongly recommend looking at alternatives.

These are brighter than the standard bulbs they replace, which was much appreciated. It should make the ballasts last forever as they are drawing less current. The light does not go out the sides quite as evenly as a standard bulb, it is a little more directed downward. Not dramatic, but a slight difference. It wold be great if the semi-opaque cover was more that 50% of the tube so the light would go more evenly in all directions. Expensive but if you want more light from your circline fixture and want to stop replacing bulbs this is the way to go.Daylight - Very good for seeing, but can be harsh.Cool white - In the middle, decent vision but not too harsh.Warm white - Relaxing light but not great for seeing detail.If you have a dual circline fixture (8 inch in the middle of a 12inch) you can use a "warmer" light on the outside (12 inch) and a "cooler" light in the middle and it is not as harsh but you still get good vision. I used a cool white 12 inch with a daylight 8 inch and it worked well for our bathroom. For a living area I would suggest a 12 inch warm white with an 8 inch cool white. I would not mix the extremes (daylight with a warm white) because the color is very different and it looks a little funky.
