This product is an Atlantic Ultraviolet Preheat Ultraviolet Lamp. It has a part number of 05-1366-R.

Preheat germicidal lamps are operated by a preheat start circuit that employs a relatively compact and economical ballast. The preheat circuit requires four electrical connections per lamp and a slight-to-moderate delay is needed to start the lamp. Some modern electronic ballasts are capable of instant starting a Preheat lamp.
