no need to be sorry, that’s what an internet message board (a.k.a. forum) is for.
First off, ask yourself what purpose you’ll want the torch for. Merely short bursts, or prolongued use?
How far would the light beam really have to reach?
What kind of cells do you have in mind?
AAA and AA cells are widespread around this wonderful planet; and nowadays we are blessed with low self-discharge rechargeable nickel-metal hydride cells (LSD-NiMH), which hold their charge considerably longer than those old rechargeables most uf use were used to. The widely preferred brand seems to be Sanyo eneloop. Even a generic charger from your local hardware store or cheapo outlet center can take care of those, albeit there are better chargers around.
Lithium technology, however, has a considerably higher “density” of electrical energy. There are primary cells, which cannot be recharged, and also rechargeable Li-Ion cells. The latter, however, are not as forgiving as your average NiMH cells, as far as abuse or mistreatment is concerned. A special charger is called for! Those, however, do not break the proverbial bank, either.
Are you looking for another bike light, a head torch, an unobstrusive pocketable torch (EDC = “Every Day Carry”), something which can be carried with a belt holster, or a handlamp with a carrying handle, even?
oh, and bicycle flashlights can be pretty decent (and expensive!), too - just take a look at the Lupine lights.
Anyways, welcome to BLF, glad you joined us!
