Cold Cathode Germicidal Ultraviolet Lamps, Tubes and Bulbs
STER-L-RAY® Cold Cathode germicidal lamps are instant starting and utilize a large cylindrical cathode instead of a tungsten filament. Due to this construction, the lamp is not adversely affected by frequent starting and the life is considerably in excess of other lamp types. Cold cathode germicidal lamps have favorable operating characteristics at reduced temperatures. They are, therefore, widely used in walk-in refrigerators and holding rooms.
STER-L-RAY® Cold Cathode germicidal lamps are well suited for disinfection of air and surfaces due to their long life and low depreciation. Cold Cathode germicidal lamps are also employed in applications where frequent starting is a requirement. Available in Low Ozone and Ozone Producing versions.

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.
