Emperor Aquatics 50W GT5 UV Sterilizer replacement lamp for Emperor Aquatics 50W HO UV Sterilizers.
NOTE: If your UV lamp is not lighting up and you've only been running the lamp for a two years or less, there is a very good chance the lamp has not burned out. Emperor lamps typically stay lit for years, but need to be replaced yearly because they lose intensity. The problem might be the Power Supply.
