Some kind of closure for prosperity:
No, there doesn’t appear to be an adapter for a hotshoe or PC connector.
There is an extender that will allow off camera and bounce flash.
But you’d still need to hack the connector.
The best way to use these other than for shooting 110 film, is probably on a 110 camera as trigger only in open flash mode.
But the use cases are pretty limited there. Lightpainting where you either wanted to catch the movement of machinery or have good IR output comes to mind.
What’s more it’s completely impossible to trigger more than one bulb without opening the cartridge to connect the bulbs in parallel, which would probably result in a pretty impressive flash.
Incidentally, does anyone know the guide number of one of the bulbs?
