TUV T8 - Guaranteed lifetime simplifying planned maintenance in professional applications Controlled UV-C output over lifetime of the lamp;Maintenance can be planned in advance, virtually eliminating the need for expensive spot replacement of prematurely failed lamps;High system efficacy ;Good environmental choice because of lowest amount of mercury TUV T8 lamps are double-ended UV-C 253.7 nm emitting lamps. TUV T8 lamps offer almost constant UV-C output over their complete lifetime. Moreover, they have a long and reliable lifetime, which allows maintenance to be planned for in advance. Short-wave UV radiation with a peak at 253.7 nm (UV-C);Protective inside coating ensures constant UV output over the complete lifetime of the lamp;Long lifetime of 18.000 hours (based on operation on a Philips electronic driver);High reliability with the lowest percentage of lamps that fail prematurely in the market (90% of all lamps still operate on full output and quality after 15,000 hrs if operated on a Philips electronic driver);Special lamp glass filters out the 185 nm ozone-forming radiation;High Output versions available for optimum UVC output per lamp length, allowing for reduction of system size;Warning sign on lamp indicates that the lamp radiates UVC Upper air and whole room handling systems;Areas with low maintenance and/or disruptive costs;Fish ponds and process water units;Open surface treatment systems
