Power Supply Requirements
Xenon short-arc lamps have a negative temperature coefficient like other gas discharge lamps. They're operated at low-voltage, high-current, DC and started with a high voltage pulse of 20 to 50kV. As an example, a 450 W lamp operates normally at 18 V and 25 A once started. They are also inherently unstable, prone to phenomena such as plasma oscillation and thermal runaway. Because of these characteristics, xenon short-arc lamps require a proper power supply.

Famous quotes containing the words power and/or supply:
“So immense are the claims on a mother, physical claims on her bodily and brain vigor, and moral claims on her heart and thoughts, that she cannot ... meet them all and find any large margin beyond for other cares and work. She serves the community in the very best and highest way it is possible to do, by giving birth to healthy children, whose physical strength has not been defrauded, and to whose moral and mental nature she can give the whole of her thoughts.”
—Frances Power Cobbe (1822–1904)
“The supply of words in the world market is plentiful but the demand is falling. Let deeds follow words now.”
—Lech Walesa (b. 1943)
