The all-glass PF1 bulb was introduced in 1954.[9] Eliminating both the metal base, and the multiple manufacturing steps needed to attach it to the glass bulb, cut the cost substantially compared to the larger M series bulbs. The design required a fibre ring around the base to hold the contact wires against the side of the glass base. An adapter was available allowing the bulb to fit into flash guns that accepted the bayonet capped bulbs. The PF1 (along with the M2) had a faster ignition time (less delay between shutter contact and peak output), so it could be used with X synch below 1/30 of a second—while most bulbs require a shutter speed of 1/15 on X synch to keep the shutter open long enough for the bulb to ignite and burn. A smaller version, the AG-1 was introduced in 1958 which did not require the fibre ring. Though it was smaller and had reduced light output, it was cheaper to manufacture and rapidly supplanted the PF1.
