Low Pressure Preheat UV Germicidal Lamps (GPH)

Preheal germicidal 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 Due to increased circuit complexity, reliability is regarded as slightly less than slim-line or cold-cathode instant-start circuits.

Low Pressure Compact Germicidal Lamps

The design of "H" shaped and "U" shaped germicidal lamps is primarily employed in application where more intense UV radiation is needed in a limited space. So it is compact. H-shape and U- shape are also instant start lamps.

Remarks: Custom designed U shape germicidal lamps are available.

Low Pressure Cold Cathode UV Germicidal Lamps

Cold cathode germicidal lamps are instant utilizing a large cylindrical cathode instead of a coil filament.Due to this construction, the lamps are not adversely affected by frequent start and the life is considerably in excess of other lamp types. Cold cathode germicidal lamps have favorable operating characteristics and maintain a high ultraviolet transmission throughout life even at reduced temperature. They are, therefore, widely used in walk-in refrigerators and holding rooms. Cold cathode UV lamps are well suited to disinfection of air and surface of unoccupied areas due to their long life and low depreciation. Cold cathode germicidal lamps are also employed in application where frequent start is a requirement.

Remarks: U shape circular shape cold cathode UV germicidal lamps are available. Custom designed cold cathode UV germicidal lamps are available.
