Levels of brightness
Brightness depends upon the type of beacon chosen, the rated power output of the unit i.e. watts and joules, the distance that the signal is observed from and the dome colour of the beacon used. In general, if the viewing distance is doubled, the light intensity observed is reduced to a quarter and if the distance is quadrupled the light intensity is reduced to a sixteenth.
A light emitting diode (LED) is a semiconductor device that emits visible light when an electrical current passes through it. The four major benefits of LED technology incorporated into warning beacons are: low power requirement, high efficiency, long life, multiple colour signals in a single beacon.
Xenon (strobe) beacons
A discharge capacitor operating through a converter circuit ignites xenon gas inside a tube creating a brilliant flash of light. Xenon gas ignites virtually instantaneously so maximum brightness is obtained immediately. Xenons have an added advantage of low current consumption combined with long life. The tube life of a xenon beacon is approximately 5 million flashes. These units are the most efficient available incorporating a 360-degree light output with the brightest and most effective vis
A parabolic reflector, driven by an electric motor, revolves around a continuously illuminated bulb on the vertical axis of the beacon, creating a powerful beam of light travelling through 360 degrees. These units are available with either a filament or a tungsten halogen bulb. In general, this type of beacon has a greater degree of light output than other models, but this is reduced as the parabolic reflector only illuminates one given point at a time .
