Classical mercury low-pressure Lamps offer an excellent efficiency. 40% of the electrical power is converted into UVC radiation at 254 nm. When using synthetic quartz as the lamp material, VUV radiation at 185 nm is also emitted.

Two lamp types with different bases, connections and lengths are available:

• Classical Mercury low-pressure lamps of high efficiency, spectrum: line at 254nm, ozone-free
• Classical UVC low-pressure lamps with synthetic quartz tube, spectrum: lines at 254nm and
    185nm, ozone-generating.

   These lamps can be also supplied as UV immersion lamps.

   It also offers low pressure amalgam lamps with increased efficiency.
