I looked at the links you provided. Do you find that the quoted "run time" for the headlight (5 hours in flash mode) is accurate?

I don't think a 3 hour run time in flash mode would be enough for me. It almost seems like the light-weight units, which are rechargeable, have short run times in general and the heavier units that use AA or AAA batteries have much longer run times. Guess I'll have to live with a heavier unit ...sigh
