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 Low Ozone and Ozone Producing versions. Shop Germicidal UV Lamps at BuyUltraviolet.com

Other sizes are readily available. Custom lamp lengths can also be supplied. Please contact us for help with your needs. Please note that ozone output is subject to considerable variation due to conditions under which the lamp is used; under many conditions, the ozone output may be only a fraction of the specified figure.
(1) Wattage is lamp watts only and does not include ballast loss.
(2) Ultraviolet output at 254 nanometers at 100 hours and 80°F (approximate).
(3) Microwatts per square centimeter at one meter from lamp.
(4) Approximate ozone output in grams per hour under favorable conditions. Figures apply only to ozone producing types.
