They are low-pressure mercury arc lamps that are the most effective tool for eliminating microorganisms such as virus, bacteria, mold and yeast in the air and impurities in water.The compact size of the lamp allows for a small system design and design flexibility.
PL-L style 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.
