Instant Start Germicidal Ultraviolet Lamps
STER-L-RAY® Instant Start Germicidal UV Lamps utilize a coil filament on each end which operates hot. Lamp life is governed by the life of the electrodes and is affected by the frequency of starting.
STER-L-RAY® Instant Start Germicidal UV Lamps are well suited to applications requiring high ultraviolet intensity such as water disinfection, air purification in duct systems and conveyorized product disinfection. Available in Low Ozone and Ozone Producing versions.

Preheat Germicidal Ultraviolet Lamps
STER-L-RAY® Preheat Germicidal UV 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.

Cold Cathode Germicidal Ultraviolet Lamps
STER-L-RAY® Cold Cathode Germicidal UV 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 UV 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 UV Lamps are well suited for disinfection of air and surfaces due to their long life and low depreciation. Cold Cathode germicidal uv lamps are also employed in applications where frequent starting is a requirement. Available in Low Ozone and Ozone Producing versions.

U-Shaped Germicidal Ultraviolet Lamps
U-Shaped uv lamps are the ideal choice for applications that require more intense ultraviolet radiation in a limited space. STER-L-RAY® Instant Start and Cold Cathode UV Lamps are available in U-Shaped configuration in Low Ozone and Ozone Producing versions.

High Output Germicidal Ultraviolet Lamps
STER-L-RAY® High Output (HO) Germicidal UV Lamps are similar in size and shape to conventional germicidal UV lamps but are capable of operating at higher UV output.
STER-L-RAY® HO Germicidal UV Lamps are widely used in forced air duct systems and water disinfection applications. High Output (HO) Ozone producing UV lamps are often found in odor control and photochemical applications. Available in Low Ozone and Ozone Producing versions.

Enhanced Output Amalgam Germicidal Ultraviolet Lamps
STER-L-RAY® Enhanced Output Amalgam UV Lamps provide germicidal ultraviolet output three or more times than that of conventional germicidal UV lamps of similar length without sacrificing efficiency or lamp life.
STER-L-RAY® Enhanced Output Amalgam UV Lamps are the highest expression of ultraviolet lamp technology and as such are the subject of ongoing technical development and improvement. Custom and proprietary designs are available to satisfy specialized needs. Available in Low Ozone and Ozone Producing versions.

High Intensity Germicidal Ultraviolet Lamps
STER-L-RAY® High Intensity Germicidal UV lamps are manufactured with a unique structure and large diameter quartz envelope which translates to more than twice the amount of ultraviolet output when compared to standard germicidal UV lamps of the same length. Available in Low Ozone and Ozone Producing versions.
