Explosion proof Medium Intensity Obstruction Light

The Explosion Proof Obstruction Light Medium Intensity 2000 cd is in compliance with ICAO/FAA/CAP437. The Light is a 2000 cd red obstruction light for Hazardous Area. 

At all radials throughout the omnidirectional 360 degrees, there must be a peak effective intensity of 2000 ±25% candela. There must also be a minimum effective intensity of 750 candela throughout a minimum vertical beam spread of 3 degrees. 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.
