UV-C Solutions Lamps and Ballasts

Advanced UV-C light sanitization with optimal performance.

Our PureFit ultraviolet germicidal lamps and paired ballasts offer cutting-edge UV-C disinfection and sterilization to protect against viruses and bacteria. In addition, we’ve taken the guesswork out of matching ballast to lamp by creating a chart of optimal replacement recommendations.

Multiple form factors

Keystone manufactures PureFit lamps in both linear and compact form factors. Linear versions come in T5 single-ended 4-pin, T5 double-ended bi-pin, and T8 double-ended bi-pin. Compact lamps are available in two versions: Compact 2-pin and Long Compact 4-pin. All are available in a wide range of wattage outputs.

Optimized pairings

Pairing between ballasts and UV-C lamps isn’t always dependable: ballasts and lamps are not optimized to work with one another and there’s no national standard. Keystone designed its ballasts and lamps to offer top performance when paired and offers a chart of replacement recommendations.
