Ster-L-Ray® Ultraviolet Germicidal Lamp
Hot Cathode Soft Glass Ultraviolet Germicidal Lamps
Hot Cathode Germicidal Ultraviolet Lamps produce short wave radiation in the range of 253.7nm (nanometers) that have an excellent germicidal effect. Ultraviolet germicidal lamps are similar to general fluorescent lamps but are manufactured with a special glass which efficiently transmits ultraviolet rays.

Hot Cathode  lamps utilize tungsten filaments, located inside each end of the lamp, which are coated with emission material and, under normal operation, govern the life of the lamp. Frequent starting of the lamp reduces the overall lamp life. Lamp is also affected by extreme hot or cold temperatures. There are several different lamps with varying lengths and watts to choose from. Most of these lamps use a miniature bipin (G5) or medium bipin (G13) base. Lamps can be used in a variety of air, water and surface disinfection applications. Call and speak with one of our ultraviolet application specialists to determine the type of lamp best suited for your application.
