I used one of them any a night when I was out of carbide lol I used a hotter bulb and ran two batteries hooked up in in series and made it much brighter . but you had to carry extra bulbs incase you blew one . I remember mine blowing one night and I had to build a fire and use my bick lighter to shine coons eyes and see my sight on my 22 rifle . got three coons out that night and it wasn't fun heading back to the truck carrying three coons and trying to lead two hounds out about 2 miles in the dark lol my hounds would normally just heal up and follow me but I didn't want to chance them hitting another track with me not having any light . I found a site called
www.lamptramp.com that still deals in old vintage carbide lamps which some of them are still new and am thinking seriously on ordering the ol just-rite carbide lamp from them .
