Sylvania 23521 6 Pack FC12T9 32 Watt 12 inch Fluorescent Circular Light Bulb, 4100K Cool White, 1800LM, T9 Bulb, G10Q 4-pin base

Mainly, it's a light bulb, haha. If you need this size/shape bulb, then this one works well and fits perfectly where my old one had been. The light flickers for a second or two when I first turn it on, but that might be due to my old fixture, or because I haven't replaced the second light bulb in the fixture. This Cool White colored bulb is very, very bright. It's probably the brightest bulb in my house now. I hadn't realized how orange my other lights are until seeing this one in comparison. I had tried finding a different color in this size but couldn't - however, it's kind of nice being able to see everything so clearly in my kitchen now. (I'm getting a surprise $5 for writing a review. I did search for a replacement light, buy it, and thought the bulb worked well.)
