I checked runime with fully charged ene-loop.
It runs about six hours in high mode.(First three hours bright and dimmer but still bright enough for another three hour)
Unlike previous model this light does't turn off itself when battery is low.
So you need to careful for over discharge when you use rechargable battery.
If you use ene-loop (2000mAh) you can have decent light for at least five
hours in high mode.:thumbsup:
I was suprized it is a lot longer than previous one.(I thought shorter than previous one)
And it doesn't suddenly turn off so safer I think.
You can see the time for the battery change a lot easier than previous one.:huh:
I am not sure about run time in alkaline battery but I think shorter than that of in ene-loop.
