Explosion proof Medium Intensity Obstruction Light

The Obstruction Light Medium Intensity is an ICAO compliance 20000 cd White for daytime operation and 2000 cd for night time operation 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.
