Nite lite stuff is awesome (coon hunters favorite II, hotlite,etc) I personally have 2 of the coon hunters favorite II and they are great 6 volt lights. 1 will run you about 6-8 or more hrs. of runnin and gunnin with the reostat turned all the way up but as they get older maybe 3 yrs they won't last most of the night and I just get a new setup and as one ages the other is fresh and if you need batteries there like $45 for a new one and keep rotating them as they get older. Just remember to keep running those batteries down all the way because if you don't they will get memory and not last as long as they should. Almost forgot I run 2 lights off of the battery... the head light and the gun light out of the recharge outlet which is nite lite too. Happy hunting
