They are supposed go in excellent flashlights such as the Wolf-Eyes Rattlesnake 4XCR123. Check it out, you can't get a better incan light for this price:I came across one of these bulbs, but the diameter is much larger than my surefires. what are these supposed to go in?
I have no idea. But given the fact that no one never mentioned such light around here, we can assume those cheap "XXX-Fire" lights aren't compatible with D36 lamp assemblies.Is there a UltraFire or SuperFire body that will accept these? I don't want to buy a expensive light just for this bulb.
