Germicidal Lamps

A germicidal lamp is a special type of lamp which produces ultraviolet light (UVC). This short-wave ultraviolet light disrupts DNA base pairing causing thymine-thymine dimers leading to death of bacteria on exposed surfaces. Germicidal UVC lamps are also used to produce ozone for water disinfection. Used in:

  • Pharmaceutical / Pharmaceutical labs
  • Food processing / manufacturing
  • Air, water, and surface disinfection
  • Hospitals
  • Laboratories
  • Biomedical
  • Micro-organism control

*Note: These types are also available in single-ended/four pin variations, designated as “-S400”.
  1. Available in standard packages of 4, 12, and 30 each.
  2. All values are nominal. Straight lamps are measured from base-face to base-face. Length tolerances are:
    • For double ended Bipin straight lamps: ±1.3mm.
    • For Slimline and all single ended lamps: ±3.0mm.
  3. Approximate output at 253.7nm at 100 hours use under laboratory conditions. These values are subject to wide variations due to application conditions.
  4. Rated average useful life is defined as the average life of a group of lamps when operated under laboratory conditions, 8 hours on, 20 minutes off.
