Intense focused beam lamp for improving visual detection
A searchlight is an apparatus that combines an extremely bright source with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction. It is usually constructed so that it can be swiveled about. The most common element used in modern searchlights is Xenon (Xe). However, Rare-earth elements such as lanthanum (La) and cerium (Ce) are used in phosphors to improve light quality in some specialized searchlights.
