This lamp is a Philips TUV PL-L 18W/4P, 2G11 base ultraviolet germicidal lamp.

TUV PL-L lamps are compact UVC (germicidal) lamps used in professional water and air disinfection units. The compact size of the lamp allows for a small system design and design flexibility. TUV PL-L lamps offer almost constant UV output over their complete lifetime, for maximum security of disinfection and high system efficacy. Thanks to the single-ended lamp base, lamp replacement is easy.


  • Security of effective disinfection over the useful lifetime of the lamp

  • Special lamp glass filters out the 185 nm ozone-forming radiation
  • High Output versions contain wind-chill correction for improved performance in moving air and reducing amount of required lamps
  • High Output versions for optimum UVC output per lamp length, allowing for reduction of system size
  • Warning sign on lamp indicates that the lamp radiates UVC


  • Deactivation of bacteria, viruses and other micro-organisms
  • Residential drinking water units
  • Fish pond and process water units
