max voltage for a luxeon III star - fliklite ls3

[fliklitelt]

hi all great forum.

I have just purchased a fliklite ls3 which uses a luxeon star 3watt led. The torch takes 2 x CR123A batteries @ 3 volt each.

I was wondering could I use 2 of the following

Rechargeable LI-ION CR123A Battery 650mah 3.7v, with the torch or would the extra 1.4 volts (7.4 instead of 6)end up either blowing or shortning the life of the luxeon star led.

thanks in advance.

fliklite.

From what I've read, some of those rechargables that say 3.7 actually come off the charger at 4.2v. /ubbthreads/images/graemlins/str.gif

I think those rechargables are designed for 1 cell lights with regulation.

Somebody correct me if I'm wrong, but I wouldn't risk it.

You could also email/PM Orb, he's on these forums. /ubbthreads/images/graemlins/smile.gif

Correct. I have two different rechargable CR123 batteries and both come from the charger at 4.18-4.19 volts. Yes, leter on they do come down under load, but I would not risk it.

Assuming you have some sort of regulating circuit in there, I think that a better (although a little bit more expensive) approach would be to get a Pila 168S, which replaces the 2 "standard" CR123's batteries. Many here in the forum use the Pila 168S with great results /ubbthreads/images/graemlins/grin.gif

No need to correct you, you're right. The indeed could provide over 8 volts to a circuit expecting 'only six', could be bad karma. Best ask the maker?

FWIW, I do disagree with 'designed for 1 cell lights with regulation' as they are designed to take advantage of specific chemistry....which is what determines the voltage.
