I don't know what wattage is but it doesnt really equate in watts as they are LED. All I know is guys were riding singletrack at the same speed as daytime so I would say the wattage is enough for almost any application. If you want to do DIY one of my customers who is an elevator repairman is bringing me some sick batteries. He ran this weekend using said same batteries and none of his guys needed a charge all weekend. They were using em for everything including around the campsite so runtimes are not a prob. They are 14V not sure of the Amp hours tho.
