At least on paper, they should be capable of the advertised run-time, possibly double that. A lot is going to depend on environmental factors.
Of course now all that is missing, is to have about 50 different flash patterns all controlled by one button that cycles through each and every mode. (So when you stop, you spend a good 10 minutes just pressing the button repeatedly to turn it off only to start cursing when you miss the "off" mode.)
Mine (Niterider) is suppose to be press and hold. But of course that function is not always easy to get to because if you hesitate too long you'll just cycle to the next mode. Why do manufactures have to make things so complicated? Is a simple on/off switch something that bizarre?
