Arc LS + AA twisty + 14500 li-ion = bright
What a timeless design, the ARC LS first run is still in the running. Add a 14500 AA sized li-ion to 1x AA twisty to ARC LS first run. you are overdriving to a estimated 700+ milliamps based upon how fast light heats up.
Thanks to pbarrette who did an analysis of ARC LS first run's circuit board and determinded that it would support up to 2amps. He ran 6volts with no damage so far to first run's board + lux.
Before I started, was fairly sure the board would not make the magic smoke. If the luxeon toasted, it could be replaced.
Measured 14500 at 3.85v, inserted into AA pak, ran for 1 sec, still OK. tried 2 sec, then 10 seconds, then 1 minute, then 5 minutes.... getting warm.
First run lives being overdriven with 14500.... so far anyways. the jury is still out on longivity.
My MM+ R2H one watt lives happily driven at aprox. 1amp, so I figure it worth a try to see if ARC LS first run makes it.
So far so good..... brightness is at least BB500 R2H in firefly. If you do this and toast your LS don't blame me or ARC. Mine is doing fine so far with no problems.
