Hi I am planning to do the through the night "ride to the sun" event in June next year. I'd like to have some good rechargeable lights to take me through the event, but I'm a bit overwhelmed by information at the moment so would appreciate some advice. I will likely be cycling from about 7pm to about 5am. Will a single charge of lights take me through the night or should I have two sets of lights? Would rechargeable lights be better than batter powered? What level of lumens should I be looking at? Does anyone have any recommendations I can look at? thanks in advance!
