Vigilant

L-856 High Intensity (White) Strobe

Application:

The Dialight Vigilant

LED L-856 unit designed for the lighting of communication towers,

smoke stacks, broadcast towers and other tall obstructions to aerial

navigation, as specified by the FAA. A high intensity system consists of

3 flash heads, 3 power supplies per level and 1 controller for the entire

system. The flash heads will be placed on up to six levels of thestructure

for a maximum of 18 synchronized flash heads for a single tower. The

3 flash heads will provide 360 degrees of coverage.

Unlike conventional Xenon flashtube technology, Dialight’s LED system

requires little or no maintenance during its lifetime, drastically reducing

costs associated with tower climbs.

Working voltages of less than

200VDC are significantly less than those of Xenon flashtube designs;

therefore, this system represents an advance in safety.

Use of LED

technology also provides a more shock and vibration resistant design,

ensuring consistent flash intensity every time.

This IP66 rated product is factory sealed to ensure water tight seals are

not compromised over the life of the strobe. Additionally, like all of

Dialight’s Obstruction Lights, patented optics provide sharp cutoff

drastically minimizing light pollution and ground scatter.
