How well I recall those old #22 bulbs. About the size of a 60 watt lamp
and a standard screw base. I wonder what practical jokers do without them?
I also recall they had more light output than any of the battery powered
electronic flash units on the market. Speaking of other uses for photo
chemistry, hypo makes a good silver cleaner. Just dunk the tarnished
silver in it a let it sit for a while.
