Steadfast� Lamp Holder sets include a stationary and a spring-loaded telescopic holder, which hold a single pin lamp securely. The spring-loaded feature on one end facilitates convenient, quick and easy, lamp changes.

Surelite� Electronic Ballast  are state-of-the-art electronic ballasts developed specifically for the operation of ultraviolet lamps. Surelite� instant start ballasts are smaller, lighter, more efficient and operate cooler than magnetic ballasts. These ballasts are silent and provide higher lamp output.

Ster-L-Ray� Slimline Germicidal Lamps � are instant starting and utilize a tungsten filament on each end. Lamp life is governed by the life of the filament and is affected by the frequency of starting.
Slimline germicidal lamps are well suited for various air and water purification applications which require high ultraviolet intensity.

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 significantly longer than that of other lamp types. Cold cathode germicidal lamps have favorable operating characteristics and maintain a high ultraviolet intensity throughout their life even 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 to 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.

The Stainless Steel housing provides unparalleled strength, durability and beauty. The attractive brushed finish stands up to even the harshest environments. The finish is polished to maximize ultraviolet intensity.
