DIALIGHT D156-A33-270

The Dialight Vigilant™ Series High Intensity LED White Strobe is the first all
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 the structure
for a maximum of 18 synchronized flash heads for a single tower. The 3
flash heads will provide 360 degrees of coverage.

Vigilant™ Series LED Based
L-856 High Intensity (White) Strobe
Unlike conventional Xenon flashtube technology, little or no
maintenance is required during its lifetime, drastically reducing
maintenance 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.
