Bike light based on a red modern power LED and CR123/RCR123?
Really sick of alkalines ruining these things.

I run NiMH AAA's in My Radbot1000s and PBSF's
They come off the charger at 1.42 volt so the pair are 2.84 only a little off the 3.2 V of a pair of fresh alkaline batteries. Fresh high voltage batteries are the key to getting light out of them.
You might want to look at this post. It says the output of the Planet bike Superflash (PBSF) drops fast as the voltage drops. I had one that had tens of hours on alkalines on my helmet and it was pathetic compared to one with fresh NiMH's. In the day, it was not viisble from 50 feet away while with a fresh set of batteries it was visble at 200 with a descending sun shining right at it (worst case). So ignore their runtime claims. Of course, dusk and night they are much more visible especially if you are in line with the beam.
I tested the output over time with 1000 mAhr NiMH cells, and now I recharge every 6-8 hours of runtime on flash (if solid cut that in half). More light, more visible, and its better for battery life not to deeply discharge them. You do give up about 15% of the brief max output you get with fresh alkalines. However, two PBSF's flashing side by side are way more than twice as visible so that is a great way to offset a little less light with the NiMH cells.
YMMV. hope this helps.

Anybody know of a good D26 dropin with a red LED and a strobe mode?
