Germicidal UV Lamps

Germicidal UV lamps emit light at 254nm (UVC), which kills or deactivates many bacteria and other micro-organisms, making it ideal for use in air, water and food sterilization and purification.  Some germicidal lamps produce ozone, which is useful for water sanitization.  Germicidal UV equipment is used en everything from large municipal wastewater treatment systems to small under-the sink systems for use in the home. 

Even though the lamps continue to light, over time, the UV output declines, making the lamps less effective. They should be replaced on a regular schedule, to make sure the system is operating at its intended level of disinfection.

Bi-Pin Germicidal UV Lamps

Short wave metal sleeve IRT lamp

Germicidal lamps with bi-pin connectors look very much like regular fluorescent lamps, but they are clear instead of frosted.  There are two types of bi-pin end caps:  mini bi-pin, where the center to center distance between the pins is 1/4 inch and medium bi-pin, where the spacing is 1/2 inch.  They are made of fused quartz, which allows the UVC light to pass through the tube.  Typically, lamps that do not generate ozone are designated "L" and those that produce ozone are designated "VH".  The number following the "T" in the part number is the diameter of the tube in 1/8 inches, so, for example, a T5 lamp is 5/8 inches in diameter.

Slim-Line Germicidal UV Lamps

Slim-Line Germicidal lamps are instant starting, and are typically made from 5/8 "T5" tubing with ceramic end caps. They are be available with single pins at each end, four pins on one end, or with two pins at each end (either mini bin-pin or medium bi-pin). Slim-Line lamps that do not generate ozone are designated "L" and those that produce ozone are designated "VH".

Pre-Heat (GPH) Germicidal UV Lamps

GPH lamps incorporate a switch that initially connects a combination filament–cathode at each end of the lamp to preheat them and requires four electrical connections. This allows the use of compact ballasts that are relatively inexpensive.  When the arc is struck the filaments are disconnected.  There is a slight delay before the lamps start.

Compact Fluorescent Germicidal UV Lamps

Just like their counterparts in general lighting, compact fluorescent Germicidal lamps are designed with multiple tubes in close proximity, to give greater power in a small area.

Medium Pressure Germicidal UV Lamps

All of the above lamp types are low pressure fluorescent lamps. Medium pressure germicidal lamps are very different. They typically produce much higher output and are much more expensive. This type of germicidal lamps is most commonly used in commercial or large-scale treatment facilities. Please call or write for more information.
