Hey all
I've been running a little experiment. Im a li-ion guy. Love them but they do have there limitations and concerns a out overdriving the led's forward voltage. So lately i've been running a downboy1000 with a single r123. Here is some results. I've compared a fully charged r123(4.1volts) against another downboy 1000 with 2x123. Both had twoj and both were in lightengies inside aleph 1 heads. With a ceiling bownce test they were of equel brightness when the test began. I then had a third aleph 1 head that had a badboy 500 and a twoj. For 30 minutes the downboy's both were of equel brightness (1xr123 and 2x123). At the 35 minute mark the 1 cell downboy started to dim. At 40 minutes the down'boy 1000 was at about the same brightness of badboy 500ma with my bounce test. At the 40 minute mark the r123 was reading 3.48 on the voltage, still plenty of juice left. I know you all may not think that 30-40 minutes off full power is a lot but for me and my edc needs it works. Plus i get to use recharable options and I get high drive currents in a small package without pushing a board and a battery to the outer limits of distater.
