Sylvania AGB3 replacement flashbulbs
Sylvania AG3b flashbulbs were very popular in the 60’s onwards as camera flash technology became easily available to the general consumer. GE and Philips and other flashbulb manufactures made similar offerings during this time. These flashbulbs had no metal base attached and connected to the camera flash circuit by two protruding wires. The “AG” designation means “All Glass”.
