Specially designed to yield the brightest warning signal over the longest duration with standard 2 new 6-volt alkaline lantern batteries (not included). Utilizing 18 clear, ultra-bright, long life LEDs positioned directly behind individual magnifier lenses more than doubles the observed signal. The rugged, compact design allows for rapid deployment and easy retrieval. Ideal to be used in groups to clearly identify a location perimeter and airport runway when power is down.

PLEASE ALLOW ADDITIONAL TIME FOR LARGE QUANTITIES.
