In the two posts above yours, I gave the camera name.

And I can relate to your story about the flash paper. My story only goes back a couple of years. My grandson lives with us and I had some of the screw-in flash bulbs. I put one in a lamp in his room expecting just a big flash when he turned the lamp on. The joke was on me though when the darn thing blew out the circuit. In addition to tripping the breaker, it fried two wall sockets which I had to replace.


Little known fact: The really old Press 40 and Press-50 Flashlamps were designed for flash guns with a maximum of about 5 volts of battery power or 22.5 Volts with a BC battery insert. When the photograhers started to screw them into light sockets with 110 Volts, after a few electrical fires and damage, the manufacturers put a fuse in the lamp base to cut the circuit within the lamp so there would be no short circuit in the line.

In the 1970s I would light a large factory floor for photography by substituting all the 150 and 200-watt light bulbs with Press 50 Blue flashlamps, opening the shutter (B) flipping on the light switch and the lighing looked perfectly natural. Exposus was f/22 or f/32 on ISO 100 film.

Leftover bulbs would be used to pull pranks around the house. 50,000 Lumins in the bathroom and 7 AM would cause a bit of havoc!

I must have had really old bulbs since the one I used to prank my grandson damaged my wall outlets. I guess it could have started a fire.
