I included a pic of the back of the package that has all the details on run time, but to answer your question...1.5 - 5 hours depending on the setting.What is the run time on them? I’ll pick up a pack for the truck too.
I hear ya, but I actually like the fact that you can charge the batteries outside of the headlamp. Once the battery runs low or is dead, I can throw in another rechargeable battery pack or some AAA's and keep on truckin'. I can recharge the dead battery pack without occupying the headlamp.I picked some up the only thing I dont care for is you have to temove the battery packs it charge.
Thats alot of opening the headlamp up but for 15 bucks I guess its is what it is.
