Explosion proof obstruction light medium intensity.

Explosion proof Medium Intensity Obstruction Light

The Explosion proof Obstruction Light Medium Intensity is an ICAO compliance 20.000 cd White obstruction light. 

At all radials throughout the omnidirectional 360 degrees, there is a peak effective intensity of 20.000 ±25% candela at daytime/twilight and a peak effective intensity of 2.000 ±25% candela at night. Multiple light units may be used to achieve a horizontal coverage of 360 degrees. The flash rate varies from 20 fpm to 60 fpm depending on the chosen configuration.
