I don't get it at all.... I have a peice of literature on these lights, but they are as confusing. I think that they also come with a remote battery pack for longer burn time (time not specified) They claim a range of 81 Lumens to 615 Lumens.
3.6 volt rech
4.8 volt recharge
6volt recharge
9volt Lithium
I think the retail is around 130.00, but I am not sure what you get for that??????
