I have the Primus lantern and it's a pretty cool gadget, but I find that despite having it with me, I've used my headlamp more. We had the lantern going for several hours off of one fuel can that never ran out, but for best use I think light that you can direct is best. Everything that I try to do with that lantern is more difficult because some of the light is directed into my eyes. After this last trip I think we will be leaving it at home from now on. Would probably be nice to take backpacking if you were with a larger group and would spend more time socializing without a campfire.
