What is candlepower?
“Candlepower is the capacity of a searchlight to produce light and does not change over distance. (Note: see PDF labeled “Candlepower Distance Chart,” which translates candlepower into distance).”
在公司資料中查看What is Lux?
“Lux is a measurement of the intensity of the searchlight beam at a specific distance, and it changes as the distance increases or decreases.”
在公司資料中查看What is the difference between a xenon and halogen searchlight?
“Halogen searchlights use a lamp with a filament and require no separate ballast, whereas a xenon lamp has an arc between two electrodes and requires a ballast. Xenon searchlights service a much greater distance because the light source is much smaller. Therefore, the beam can be concentrated into a much smaller, narrower beam on demand.”
在公司資料中查看What is a metal halide searchlight?
“This is a searchlight which uses an arc lamp, similar to a xenon arc lamp. However, metal halide lamps have a warm-up cycle and take anywhere from 30 seconds to 1 minute for the beam to come on.”
在公司資料中查看Does LED technology replace xenon technology?
“No. Although the development of LED technology has come a long way in recent years, it still can only service a small fraction of the great distances achieved with xenon searchlights.”
