cheers guys i understand that you gets what you pays for regarding these lights but as im starting out a light with a burn time of 90 mins is about how long the ride takes and the first 10-20 minutes i can do without a light as we are all riding next to each other so the path is lit up from the bright light my mate has. its when we get a bit further in that we get a bit spread out as my fitness is crap at the minute that i could do with some light
