Review on Sylvania 20318 Compact Fluorescent 4 Pin Single Tube 4100K, 13-watt: Efficient Lighting Solution for Any Space by David Holmes

I have two sconces in my bathroom that use these bulbs. One blew up after almost five years of use. I bought a replacement not realizing that I had warm bulbs and the one I bought was cold. And it was VERY cool and gave off an eerie blue glow that definitely didn't match the warm yellow glow of other sconces. I searched my entire city and couldn't find a single warm lightbulb that worked in a sconce, so I turned to Revain and quickly found the exact lightbulb I needed. I ordered it and it arrived quickly and matched my other light bulb perfectly. Hooray! So I ordered seven more. It's supposed to last 20 years. I'm very happy with the performance of these bulbs, I especially like the color which is very similar to the color of incandescent bulbs. From an ecological point of view, this may not be good. It has a large plastic base and it is not known what metals are inside. However, the box can be recycled. Not sure if it evens out. . . .
