Straight pulsed xenon lamps have a diameter of 11mm and overall length of 172-390mm, depending on wattage. The lamps are equipped with special cable connections.
The spectrum of their radiation output os, like that of all xenon lamps, near-continous, ranging from about 200 to 1000nm.
The colour temperature is 5600k.
Pulsed xenon lamps are operated on a ballast circuit of the semi-resonant type, in addition, they need an electronic ignitor to provide the starting pulse of some 10kv~30kv and, for the higher wattage, a transformer to step up the mains voltage to the required lamp voltage. They have instant ignition and re-ignition and require no warming up time.
The average rated life ranges between 250 and 500 hours at a depreciation of 20% after 250 burning hours. PS lamps need forced-air cooling.
They do not emit any ozone. Since they emit short-wave UV radiation, they must be screened to protect the high starting voltage, the lampholders must be insulated from the luminaire.
The burning position is universal.

脈衝氙燈 是利用貯存的電能或化學能,在極短時間內發生高強度閃光的氙燈。19世紀中葉,F.塔爾博特首次應用火花隙放電作為高速攝影的曝光光源,這是最早的人造脈衝光源。以後出現了惰性氣體脈衝放電光源,才使脈衝光源真正進入實用階段。1935~1945年,一系列脈衝光源在商業市場出現。50年代,脈衝光源進入工業領域。脈衝氙燈一般由密封在玻璃或石英玻璃體內的兩個電極組成,殼體中充以氙等惰性氣體。脈衝光源的閃光持續是指1/3峰值光強所對應的時間間隔,稱為脈衝寬度。它主要由光源的結構和點燈電路決定。現有脈衝光源的脈衝寬度一般為10-9~10-2s,瞬時亮度可達1010cd/m2,是除雷射外亮度最高的人造光源,它的瞬時光通量可達109lm,閃光重複頻率為1~106次/分,工作壽命達106次以上,發光效率為40lm/W。
它是瞬間脈衝放電而產生的光。
