Since 2012,Star Standard has designed and manufactured industry-leading aviation obstruction lights(also called “aircraft warning lights) and navigational aids for a variety of industrial uses. We provide critical lighting and hazard marking in the toughest conditions around the world, with clients ranging from EU, Southeast Asia, South Latin America,etc., to corporations and municipalities. Our obstruction lighting products are manufactured in ISO 9001:2015 certified facilities in China.
Obstruction lights are widely used in such places as broadcasts,cranes and infrastructures,marines,mining,railyards,telecommunications,etc.
The classification of aviation obstruction lights is as follows:
a) L-810, low-intensity red obstruction light
b) L-856, high-intensity white flashing obstacle light, 40 flashes/min
c) L-857, high-intensity white flashing obstacle light, 60 flashes/min
d) L-864, medium intensity red flashing obstruction light, 20 flashes/min-40 flashes/min
e) L-865, medium intensity white flashing obstacle light, 40 flashes/min
f) L-866, medium intensity white flashing obstruction light, 60 flashes/min
g) L-885, medium intensity red flashing obstruction light, 60 flashes/min

Aviation obstruction lights are generally divided into low intensity, medium intensity and high intensity. The vertical and horizontal distances of aviation obstruction lights are greater than 45m for buildings and their facilities, and the three types of obstruction marker lights can be used in conjunction with each other. Aviation obstacle indicator classification
Below 45 meters above the ground, low-intensity aviation obstruction lights should be set up in relatively open surroundings, which are always bright red.
Buildings and facilities 45m above the ground and 105 meters below the ground: use medium-intensity B-type aviation obstruction lights as red flashing lights, the flash frequency should be between 20-60 times per minute, and the effective light intensity is 2000cd±25%.
Use medium-intensity type A aviation obstruction light above 105 meters above the ground and below 150 meters; white flashing, effective light intensity (2000-20000cd) ± 25%.
For buildings and their facilities above 150 meters from the ground, use high-intensity obstacle signs and must be white flashing lights. The flash frequency should be between 20-70 times per minute. The effective light intensity depends on the brightness of the background. It works 24 hours a day.
Obstacles should mark the highest point and the extreme edge (ie, apparent height and width) of the obstacle. The distance between the middle layer must be no more than 45 meters, and the height of the city should be more than 100 meters. Special consideration should be given to adding aviation obstruction lights to the middle floors of buildings.
The vertical and horizontal distances of aviation obstruction lights should not be greater than 45 meters (that is, if the top of the object is more than 45 meters above the ground, the beacon must be obstructed in the middle)
For chimneys or other buildings of similar nature, the top obstacle marker light should be located between 1.5-3 meters from the top, taking into account the pollution of the chimney to the lamps.
The obstacle indicator light can be located 4-6 meters below the chimney mouth.
Ultra-high objects higher than 150 meters should be used in conjunction with medium and high-intensity aviation obstruction lights.
For high-voltage power transmission cables and towers less than 150 meters high, a white light-emitting medium-intensity aviation obstruction light can be installed on the top.
Regardless of the aviation obstruction lights, the number and arrangement of the aviation obstruction lights at different heights should be able to see the object or the “group outline” of the object from all aspects, and consider the simultaneous and sequential flashing of the obstruction lights to achieve Obvious warning effect.

According to regulations from the Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO), any structure that exceeds 45m above ground level is required to be properly marked with aviation obstruction lights. Tall structures like towers, industrial chimneys & smokestacks, and even wind turbines will need to adhere to minimum requirements in order to meet safety regulations.
The height of the structure is only one factor that must be considered when choosing how to place aviation warning lights. Structure diameter, weather, terrain, proximity to airports, and other considerations will ultimately determine the required obstruction lighting setup.
Industrial Access can help establish the proper aviation obstruction light configuration to keep you up to code and within regulations. These warning systems require special attention as regulations continue to evolve. Since requirements may vary depending on your location, the type of structure, and environmental concerns, it’s best to consult with a professional that has specific knowledge of regulation & installation requirements.
Star Standard’s R&D team of highly trained rope access technicians can quickly & efficiently install, maintain, and repair aviation obstruction lights on your tall structures or industrial chimneys. Contact us today so we can assess your high angle needs.
