💡 Sylvania CF13DS: Powerful and Energy-Efficient 13 Watt Compact Fluorescent Bulb Review

I bought these because they were longer than others I've had and some bulbs I took out burned out where they were longer. After I bought them I found that the shorter ones would work just as well as it's all about the base and not necessarily the length. They fit and I haven't had any problems.

Cannot compete with such a small lamp for less than $2. I ordered ten because I knew all of my bulbs would burn out within a month. One was already off, of course, and the other went off the day after I turned on the light. These lights are very bright, 4100K, hard to find bulbs brighter than these, they probably don't make them anymore. I hope to use them for at least 2-3 years which suits me well. If you buy these headlights I am sure you will be satisfied.

They just work. I'm always a bit apprehensive when ordering similar items online for fear that they won't be compatible. But they came as advertised and now I have a large supply to use and share with my neighbors. By the way, you usually hear that fluorescent lights last a very long time, but I don't think they last much longer than some old incandescent bulbs. I suspect the bulbs are fine, but the "conversion" in the base (power supply? transformer?) is designed to take less time.
