Mercury vapor lamp, low pressure
Low pressure mercury discharge bulbs are sealed Quartz tubes containing Mercury vapor mixed with Argon. An arc of electricity efficiently produces a discharge of radiation in the 253 -185 nm ultraviolet region. Low pressure mercury vapor lamps are used as germicidal lights and as cold and hot cathodes.
Most bulbs have an outer saftey glass to minimize UV radiation.
