What is the run time . . . 15 minutes?
I have a single XML T6 LED light on the helmet and it is plenty bright. A similar power light on the bars to light the road. Five LEDs seems like overkill. Maybe if there were modes for 1, 3, and all 5 LEDs. Then you could save the max lumens for "emergencies".
If your responding to the 5800 lumen monster I posted about, it is 7, yes SEVEN, CREE LEDs, NOT a measly 5.
I think 7, or 5 LEDs, and anything close to 5800 lumens or whatever this thing actually puts out, is serious overkill and nobody should really use this while communing anywhere that they might encounter other living people on the way.
I guess sarcasm is harder to pick up on in a forum, particularly when I am sure there are some BF members who are ready to buy a couple to light up the night.
As for battery life, the manufacture claims 2 hours, guess its a big battery pack. I also assume that they are overestimating that, just like I am sure they are over estimating the lumen rating.
