I've swapped out my UltraFire B3 torch (also from DX) for another Fenix E01. While walking back from the stream that I couldn't safetly jump across (damn my short legs
) I was just using said tiny torch. I realised that the E01 and B3 throw out enough light for anything I'm likely to be doing other than search and rescue.
The day before yesterday I found my B3 can overheat or short (not sure which, but it's a bitch to disassemble anyway) so I figure it's not reliable enough. My C3's aren't 100% reliable so need to be phased out. I think they have a problem with a short somewhere, if it doesn't work, I have to strip it down and then it works fine, but I've not figured out what's shorting on what.
I'll be migrating all my torches from UltraFire, probably to Fenix, although I'm going to try a Romisen or two (given Brit-ZedHunter's positive review and the writeup on CPF). I was considering replacing my Krill with a Glo Toob, but given the E01's light output and runtime, I'm more likely to replace the Krill with more E01's and spare lithium AAA's. I wish Fenix did a proper diffuser for the E01!
EDIT: The E01's have a serious purple tint. I mean it's not white, it's light purple. It's annoying from an asthetics point of view, but of little consequence for my usage. Just a heads up to anyone thinking of buying one. They can be modded with wire wool to give a more even white beam according to a CPF thread, but I won't be bothering. If I point this at the ceiling (it'll happily stand on it's tail), it illuminates a larger area than my Krill Extreme 360. It's waterproof, small and seriously tough. Also, supposedly you can use the cap of a lip balm stick as a diffuser.
