The AG-1B bulb was introduced in the late 1950s and offered some innovations over previous bulbs. These bulbs are much smaller than other flashbulbs, allowing them to be more easily used on smaller cameras such as Minox, or 110 and 126 Instamatic cameras. The "AG" apparently stood for "all glass" as these bulbs are without a metal base and the filaments encased in a one-piece glass shell. The AG-1B produced about 330,000 lumens at its peak output (about 15ms) and was most commonly used in a 2-3" reflector with a range between 5-20 feet. As a fun side note, the AG-1 bulb was also popularly used in model rocketry to serve as a means of igniting the rocket engine.
Because clear bulbs were designed for use with black and white films, the "B" style bulbs such as the AG-1B were designed with a blue coating to assist in color correction when using flash with color films. Because of this coating, these bulbs may operate with 1/2 to 1 stop less light output as their clear counterparts.
