For those of you who remember them, Choinard, now Black Diamond used to distribute and sell a red headlamp with a 2 3/4" reflector, a red battery pack on the back of your head, with the wire and battery pack connected by a neat rubber headback with ventilation holes cut into it.
It was my main headlamp for the last 20 years until I replaced it with one of the "toy" 4 LED headlamps. I decided to take it out of its role as backup headlamp and discovered that the bulb lights up, but VERY dimly. This headlamp takes either 1 D alkaline, or 4 AA's in a plastic adaptor. Using 4 new lithium AA's, and a couple of fresh D cells, no dice. Still comes on dimly.
Changed the bulb, still lights faintly.
I checked to see if the copper contacts anywhere were loose or if anything is corroded, still, no problems. In my view, this is one of the best headlamps every made, and I'm not ready to junk it. The case says it was made by the Easter Seal company of Hartford CT.
Anyone familiar with this lamp? Any engineers or tech types care to offer advice on how to save this headlamp's life? Its a really good piece of gear, light for its size, taking regular or lighium batteries with cheap bulbs and throws a ton of light.
