I am interested to hear about your set up once you get it going.
For 24 hr races I guess you need more powerful lights for tired eyes and to blind your competitors
I have the Alphas on the bar with the wide beam and the spot on the helmet. Both running the smaller batteries.
I climb in the low setting to save juice for the descent, so I can get a 3 hr ride in no problem with plenty of light on a solo rode.
I am thinking if getting a spare battery to carry just in case.
Do you think the bigger battery is better then 2 of the smaller batteries? Switching would be a pain if you are flat out racing. This is not an issue for me as I only go in events to finish the challenge.
The X2 or brighter would better for the wide beam lens.
