Velda Uv-C PL lamp 9W

A UV-C PL lamp is an integral part of a UV-C unit, which is used to keep aquariums and ponds free of floating algae, and to reduce the number of bacteria by means of UV-C radiation. When the light output of the lamp decreases, it is advisable to replace the lamp. Please note that the optimal PL UV-C output expected from UV-C lamps will not be achieved for a week or two. The output of these lamps is 30% higher and their lifespan is 30% longer than that of regular models.Note: Be aware that ultraviolet radiation is very dangerous to the eyes and skin. Always switch off the power supply before installing or cleaning.
