Streamlight Lantern

[JazzDad]

Does anyone have a wiring diagram for a Streamlight lantern? What is with the dual-filament bulb? (Three wires going to it, that may sense the resistance.) I want to replace it with a regular sealed beam I have.

Spot light vs flood light I believe it's the reason for the dual filament.

Streamlight built models that had dual filament bulbs so that when one filament blew, the switch could be flipped and the other filament would light up. It was a failsafe.

 

[JazzDad]

So their circuitry feeds one filament, then the other if the first one burns out? I put a DVM on each of the (I assume to be) positive leads (grey and black) going to the lamp. Both read 0V. I am assuming the green wire is negative.

I don't think there is a spot & flood pattern - there is only an on/off switch.

No, I thought the switch was dual throw but it's been so long since I researched it, I'll have to try and look for the info.

Any help is appreciated.
