Too low capacity, the risk that a short somewhere in the flashlight makes the ultracap explode (fun pastime if it is not in your hand) and high price compared to a comparable pack of eneloop batteries and a charger.
And they do self discharge and rather fast compared to a LSD battery as the eneloop.
The upside is no memory effect in them and the fast charge time.The latter being a mute point if they had a proper capacity in the first place.
I see it as a specialty item indeed.
Of course it would be wonderful if the apperance of such flashlights could drive the development of even better ultra caps in which case we will look at thread and laugh in a few years.
the ultracap of 405g61x81mm can give 1200 farads at 2,7v aka drive an xml(3,2v) at 3A for ~5 minutes ...mmh them should improve to use it on flashlights
I can make mistakes pls confirm :)
btw that capacitance is whopping if you take it on your body XD them can make a self defence flashlight but maybe will be illegal...
But I would buy it just to power a led of 200watt for a pair second xD ..ya reading the price >200$ of a thing like that I can change my mind but would be cool
Can't get pass the blowing off my hand risk. Really fond of my hands.
I was a lightweight I guess, only used piezo cigarette lighters & piezo barbecue igniter for the big guns. Great for relieving stress in your shoulder muscles. Swear I can stop anytime. I don't have a problem...
Anyone see those cool battery based barbecue igniters? 200zaps/min!
LOL on the piezos. Those worked great on the legs of the school chairs, transferring the spark through the steel bolts in the wooden seats.
The worst (best?) one for me was discovered at the tender age of thirteen. It was a silver book, on the smallish side at ~5x7 inches. On the cover was the German proclamation 101 Sexuelle positionen...of course I picked it up !
Suddenly, my arms were paralyzed - I was gripping the book with two electrified claws, and nearly unable to drop the surprisingly powerful prank.
As it turns out, the silver cover was to increase electrical conduction of what was a crude alternating-current stun-gun-in-a-book !!!
