Default LED Flashlight Review

I find those sizes very hard to believe. Even a one farad capacitor
is pretty large and in some cases, larger than an average flashlight.



Depends upon the working voltage. I had seen 1 farad caps 20 years ago
that were not much larger than a couple of small mercury cells. I'm
sure they've gotten them even smaller by now.



True. I forgot about the voltage aspect, as I was thinking about the
sizes used by the auto sound nuts in their vehicles. A one Farad size in
those applications is about the size of a one litre (about a US Quart)
container. I can't imagine a hand shaken flashlight would make enough of
a voltage to allow a size reduction of any great magnitude..

I'm probably wrong, so please post any more information you may have
access to.

As for those car stereo lunatics, I think they will all be deaf after a
few years. I can hear their bloody bass five cars away. How can the use
of headphones by a car driver be illegal when that megawatt idiocy is
allowed to continue?
