I had a question about the run time of this light. I swear the one I bought a few years ago at walmart was 50 hours on low or the single led setting and 100 hours on high or both leds. It seems the newer ones are 100 and 200 hours. Did they charge it? Is it brighter, dimmer or did they just realise that usable light was being produced so the initial ratings were wrong? I have one and used it during hurricane isabell last year. I used the low setting for 2 nights as a night light. It worked fine. In total darkness I could not see much of an improvement running it on high or both leds, so I settled on low or the single led setting.
