I`ve got one of them, it`s a nice enough little light but I have to agree that the brightness levels are too close together. It starts with 3 LEDs which is pretty bright, and on 7 it`s about twice as bright, maybe not quite twice due to the extra strain on the 3 AAs. In between, the step from one to the next is barely noticeable. And if you keep turning past the full power setting, it goes out again which can get annoying if you want light quick and can`t be fussed fiddling to get it in just the right spot. The switch points are close together, a quarter turn cycles them all. The head is stiff and not easy to turn with one hand, though not impossible.
My biggest problem with it? It`s a flickery little bugger, that`s what. Flickers like mad when you turn the head. It seems stable when you quit turning though, I`ve had no problems there except after a fall. Usually flickers and goes out if you drop it, and it doesn`t seem too durable. I`ve "drop-tested" it (yes keep telling myself it`s another "drop test" and I won`t feel so damn clumsy
) a few times, every time the battery contacts got all squished in and once the head and switching assembly came off and bent all the little contacts inside too so it went seriously screwy for a bit. Straightening them out restored normal operation though but I can see long term reliability troubles occuring in this one- too many sliding contact surfaces that could wear or tarnish.
It`s overpriced for what it is (not even resistors in there
) but kind of neat too. It`s certainly unique, the way the LEDs wink on and off in different patterns when it`s being turned is fun to watch- and it`s bright too (maybe close to the Tektite 300 and Night Buster 8X but I have neither yet so can`t comment) it`s just not the best out there. Too bad, it cost me a small fortune
