Match Light Intensity to Obstacle Height
Height ≤ 45m: Select a low-intensity light as a supplement paired with a medium-intensity Type B light as the primary warning light; low-intensity lights must not be used alone.
45m < Height ≤ 105m: Select a medium-intensity Type B flashing red light; suitable for standard high-rise buildings, medium-sized communication towers, etc.
105m < Height ≤ 150m: Select a medium-intensity Type A flashing white light; suitable for areas with high background brightness, such as super-tall office buildings or large bridge towers.
Height > 150m: Must select a high-intensity Type A light capable of 24-hour, all-weather operation; medium-intensity lights cannot be used as substitutes.
Select Specialized Models for Specific Environments
Remote areas without mains power: Select a hybrid mains/solar model; ensure an autonomy of at least 7 days during overcast or rainy weather.
Coastal areas/Chemical industrial parks: Select specialized models with an IP66 or higher protection rating and features such as salt-spray resistance and explosion-proof capabilities.
Urban core areas: Select low-glare, silent models to avoid disturbing residents with light pollution.
Verify Compliance and Certification for Acceptance
Prioritize products holding CAAC (Civil Aviation Administration of China) certification and compliant with the MH/T 6012-2015 Aviation Obstacle Light standard; ensure parameters such as light intensity and flash frequency meet regulations to guarantee successful acceptance by civil aviation authorities.
