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:
“We are born to action; and whatever is capable of suggesting and guiding action has power over us from the first.”
—Charles Horton Cooley (1864–1929)
“There never has been a time in our history when work was so abundant or when wages were as high, whether measured by the currency in which they are paid or by their power to supply the necessaries and comforts of life.”
