Burning position

LTI’s xenon lamps may be operated vertically or horizontally. In the vertical position, the anode is at the top, and the cathode is at the bottom. The arc burns most smoothly in this position; the configuration is rotationally symmetrical. Lamps operated in the vertical position may be tilted, however, it is recommended that the tilt angle be less than ±30 degrees.

In the horizontal position, the arc burns less smoothly and, without arc stabilization, may result in hastened electrode wear. While the rotation is not wholly symmetrical as in vertical operation, it is a necessity for some lamp housings. Every lamp designed for horizontal operation may also be operated vertically.
