I think that is AA though...I also have a UK SL4, but I haven't noticed that it is that much brighter than my scout-type lights even though it uses 4 C cells.. I can make you a good deal on a slightly used 747 fuselage that has been converted into a halogen canister light if you need more light or need your back realigned..Mo2vation once bubbled...
I got no prob with the utilitarian purpose of this thing. Its very vanilla. Very beige. Very Manilow. I got no issues with that. It does its thing and will do it all the time.
End of the world, cockroaches and the Scout light. I got it.
So back to my quest - I want the brightest hiroshima solar flare I can get in a 3-C size.
Is it Pelican, UK, Princeton, what?
