WitrynaWhen that happens, up to 50 mg of mercury vapor is released into the atmosphere. This quantity of mercury is potentially toxic, but the main hazard from broken lamps is glass cuts, and occasional exposure to broken lamps is not expected to have adverse effects. WitrynaIt is important for water disinfection since the size of mercury lamps may be too large to install in the system. Mercury lamps need to be heated up, which is a step skipped by UVC LED users since they can start working at once. As for the lifespan, UVC LEDs can last much longer than mercury lamps.
