The short arc Xenon lamp is a sort of point source having very high luminous intensity and a continuous spectrum from ultraviolet to IR.
短弧氙灯是一种发光强度高，具有从紫外到红外的连续光谱的点光源。

I think they arc in a kIttcr position in those sportS that demand a high degree of intensity, speed and explosive force like swimming, field games, etc.
我觉得，他们更适合那些高强度、高速度、爆发力强的项目，如游泳和田径。

Unlike Halogen lamps, High-Intensity-Discharge (HID) lamps don't have a filament but create light by the arc between two electrodes.
