SUNLIGHT SERIES
This lamp is a self-ballasted mercury lamp, a type of the HID(High Intensity Discharge) lamp. Its radiation spectrum contains medium wave ultraviolet UVB, long wave ultraviolet UVA, visible light and infrared ray. Its spectrum characteristic is similar to solar spectrum in alpine areas. In order to improve lamp working efficiency, we can make reflector bulbs with evaporation of aluminum,frosted or rough surface.
