Ster-L-Ray® Ultraviolet Germicidal Lamp
Ster-L-Ray® Preheat Germicidal Ultraviolet Lamps
STER-L-RAY® 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. Available in ozone producing and non-ozone producing versions.
