TUV PL-L - Compact solution for professional applications Controlled UV-C output over lifetime of the lamp;High system efficacy TUV PL-L lamps are compact UV-C lamps emitting a peak at 253.7 nm. 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. Thanks to the single-ended lamp base, lamp replacement is easy. Short-wave UV radiation with a peak at 253.7 nm (UVC) ;Protective inside coating ensures constant UV output over the complete 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 Residential drinking water units;Fish pond and process water units;In-duct air treatment units;Stand alone air handlers
