Philips TUV lamps are compact UVC (germicidal) lamps used in residential water, air disinfection and pond filter units. The compact size of the lamps allows for a small system design and design flexibility. Philips TUV lamps offer 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. The TUV PL-S & TUV PL-L lamps have a useful life of 9000hrs.
