runtime? I dunno, 20 minutes on high? Twice that or more w/ good 26650 instead? Maybe someone smarter will tell you more accurately.
as for building your own, check out the threads on saik sa-305. $15 host, $8.6 emitter, $5 driver, and you'll probably want a reflector. Figure in your time, the risk of screwing something up, and that it won't be nearly as nice of a host and $45 starts to sound pretty good.
Sorry, to cause this thread to run off-topic. I know the 7135 drivers are linear and just burn off extra voltage. I meant 4AA with a driver which could make better use of the extra voltage for runtime (or possibly allow better use with alkalines).
Only thing that it could have more modes, something like 5 modes with moonlight etc.
I do know that ZebraLights are pricier, but you get warranty, versatility, high efficiency and versatility(again), IMO there is no other single AA headlamp-flashlight combo that offers as much as ZL H51, BUT as already mentioned, 60$ is not little money for some, me included, tho if it has superb build quality and lasts forever, why not?
Amen...I bought the UF version a few weeks ago on Ebay, as I really wanted one...$47 + 14mm XM-L emitter + driver. I've never ever been accused of having good timing :)
Crap, I already spent $65 on lights today, and you guys start flashing pictures and praise for an AA light (my favorite). I need to take a BLF-vacation for a month and let my paypal account cool down to normal operating temperature.
Well, I wouldnt mind to get one for 30$ shipped, 35$ doesnt seem like too much either, but 30$ might many here consider about getting actually 2 of these IMO :D!
45$ on the other hand is a bit too much, for that price or some additional 10-15$ you can get decent 2xAA light from known brand that has warranty.
If the quality is up to the original Ultrafire standards then $45 is already quite the steal. I’m sure Hank shelled out quite a chunk of money to have a custom run of these lights made. You are already saving $15 by not having to mod the light.
I Would agree that the price is Just right. Hank's been doing a lot of us a favor selling a light most of us have been trying to acquire on stock to Mod.
Kudos to Hank for providing custom lights with budget price. Would have gotten one if I only have spare funds.
Anybody bought one yet? would love to see a review.
