ZOM-75W. Low Intensity Obstruction Lights, Type A. Technical description

ZOM-75W >10cd, 220V 50Hz.
ICAO Low-intensity, type A Obstruction Light


ZOM-75W low intensity obstruction light is a light signaling equipment module, combining excellent optic-physical characteristics, vandal-proof frame and availability. This item proved itself to be a reliable solution with excellent performance data. Model was introduced in 2006 and no warranty claims were made during the last service period. Advantages of this model are as follows: modern shock-proof frame and attractive price. This obstruction light model has a design, identical to ZOL-2 obstruction light, manufactured by GSTZ till 1991. Quality supervision on all manufacture and shipment stages provides complete exclusion of defective goods claims.

Purpose of the device:

ZOM-75W low intensity, type A obstruction lights are intended for marking high-rise objects (obstructions) potentially dangerous for air traffic: tall buildings and structures, smoke-stacks, telecommunication towers, mobile communications relay masts, water towers, chimneys, power lines, cooling towers, crane installations, bridge supports, structures located in airports vicinity.

Key features:

  • Easy to install, several mounting sets available;
  • No RF-radiations;
  • Ten (10) years warranty;
  • Patented.


  • Simplicity of design;
  • Low price.

Specifications met:

  • ICAO International Standards and Recommended Practices: Aerodromes Annex 14 Volume 1, 5th Edition, July 2009, Chapter 6: Low-intensity, Type A Fixed Obstacle Light.

General requirements to installation and exploitation:

ZOM-75W low intensity obstruction lights are attached by means of a carrier unit (tubular mast) with outer threading G 3/4. ZOM-75W obstruction lights contain a 40W electric incandescent lamp which requires replacement if burned out during the service life duration. Upon ZOM-75W low intensity obstruction lights assembly it is necessary to observe that the rubber seal is installed in place. Light filter cleaning is to be performed if and when it is contaminated by means of clean cotton, soft flannel or wash leather without any solvents and abrasive substances. After cleaning the light bowl is to be wiped by cotton, slightly moistened in alcohol.

Assembly types:

Obstruction Light sale


Obstruction lights packing under GOST 23216 for storage conditions 2 (c) GOST 15150. ZOM-75W obstruction lights are packed in transport tare, providing protection from mechanical damage and atmospheric condensation.

Accident Prevention:

In order to ensure safety during exploitation of ZOM-75W obstruction lights it is forbidden to:

  • Replace the lamp with light sources having lower luminous intensity index;
  • Perform any works on ZOM-75W obstruction lights while voltage is connected
  • Assemble and operate obstruction lights with compromised insulation.

Manufacturer's warranty:

We guarantee faultless device operation during 5 years in case of service regulations compliance!
