I'm sure this is posted somewhere, but my Google-Fu is quite lacking and I couldn't find any results.

I'm testing out a KL1 head with a SF E1L. I get at most 37 minutes with 2 different brands of RCR123A's before the LED starts blinking slow. Measured voltage when I pull the batteries is 2.5v.

Runtime was a mere 37 minutes.

And - I was able to duplicate it with a different branded battery.

Output was great for most of the 37 minutes, then it just dumped downwards rapidly.

I would have thought that it would have lasted just a bit longer - like 1 hour. Or am I expecting too much?

Has someone else done any runtime charts with an E1L/KL1 high dome and RCR123A's?

Thanks,
Steve
