Feit Electric BPESL15T/BLB 13-Watt Compact Fluorescent Twist Bulb (60-Watt Incandescent Equivalent), Black Light Blue

Comment: After a couple other UV bulbs had failed to cure my two-part epoxy even as fast as the sun on a rainy day, I followed a friend's recommendation and bought the Feit. It cured the epoxy in a couple of minutes, exactly as required. The recommended UV cure light system was going to cost almost $1000; the Feit fits into any incandescent lamp and works almost as well for almost $990 less.

I'm not sure what else you use these things for, but this will definitely stay on top of my list for UV adhesive curing.

Comment: Screwed in the bulb, turned on the switch, and my children were delighted. Works just as you hope it would. One thing to keep in mind though, this is a small black light, equiv to about a 60 watt bulb. By itself, it will obviously not perform as powerfully as a 100-200 watt fixture. But that's not what we want here. With this bulb, you can now do black light on a whim, where ever there is a socket. I swapped out all the lights in the kids bathroom for quite the tooth-brushing treat. They will never look at their mouths the same way again!.

Comment: I'm reading all these positive reviews and saying to myself, Something's not right here. I bought one of these and it DOES NOT work well. Sure, if you compare it to an "incandescent bulb," which too many other reviewers suspisciously do, it is marginally better. But if you compare it to a full size black light fluorescent tube, this CF version is sorely lacking. This bulb, used with or without a shade, does not make white, like your teeth or on your clothes, glow brightly. It only marginally makes bright colors pop. The black light effects are not obvious; you have to really look for them. If you think you're going to use these at a party and everyone freaks out, forget it. I think the problem is the bulb is too bright. You would think it makes sense that a fluorescent light, even in CF form, would make black light work better, but it is a poor substitution for "real" black light fluorescent tubes.

Comment: This thing works very well, I even compared it to my 18'' station and it was almost as bright.

Comment: I got 3 of these for exterior lighting around Halloween and they look great. They give off the real ultraviolet light that makes the whites glow unlike incandescent bulbs. The only reason i did not give this a 5 Star is because of price per bulb.
