Why hasn\'t anyone made a sub c led torch?
Well I may not be as experience in torches as almost all the members in this community but I wonder why hasn't anyone thought of powering torches off a rechargable sub c nimh cell. It being 42.5mm long 22mm in diameter and currently having a nominal capacity of 3800mah now. to compare 2 123a batts each having the nominal capacity of 1000 mah running at 3volts to 2 sub c rechargable cells. I will times the mah
by the voltage, though not a perfect comparism due the the inefficiencies of power regulating chips. we will get; For 2 123a cells 3 * 2 * 1000 = 6000 however for 2 sub c cells it is 2 * 1.2 * 3800 = 9120 which is more then 1.5 times the figure even in factoring the approximate 80% eff of a regualting chip it will still provide longer run times. The out put of the sub c cell can easily with stand 30 amps though in rc car usage it can hit 50 amps and above. It can be charged safely at 4.5 amps meaning charging time is less then an hour. Hence it is better then any pila rechargable cell. Though it is wider then most conventional ''mini'' torch cells, it is still very small in diameter and its length is shorter then an AA cell. 85mm for 2 cells vs 100mm for 2 aa cells around 9.5mm longer then a 123a cell. So pardon me for asking, hope I didnt ask a stupid question as I'm extremely new in the world of led lighting and am currently taking it up as a hobby. I only own a L4 and xm-3 at the moment an am thinking of getting an aleph le 2 with 2* 123a . However I am wonder about the aluminum quality of the torch, I have back ground in rc car racing and I realise the alloy type of aluminum is very important to the hardiness of the light for example the xm-3 I have is made up of very soft al alloy which dents easily, the best would be the 7 or 2 series which nobody seems to use due to its cost and most use 6 series alloy though chemically more resistant to corrosion, rather soft. It doesnt really matter as now torches are hard anodised protecting them from corrosion but if the aluminum is soft even hard anodizing won't prevent dents, does any one have any views on the battery issue and the aleph hardiness pls enlighten me. Thanks for your time. God Bless CPF
