This FAA Type L-810 red obstruction light is a low-intensity incandescent lighting solution designed to mark aviation hazards such as towers, buildings, and other tall structures that require nighttime visibility for aircraft safety. Engineered to meet FAA L-810 specifications, this obstruction light delivers a minimum effective luminous intensity of 32.5 candelas and provides full 360-degree horizontal coverage with a vertical beam spread of at least 10 degrees. It is powered by two 116-watt incandescent lamps operating on standard 120V to 240V AC at 50/60 Hz, drawing approximately 2 amps of current.
Built to withstand harsh environmental conditions, the light features a durable construction with a cast A356 aluminum base and a Fresnel Pyrex glass lens that enhances optical performance. Stainless steel hardware, including latches and a safety cable, ensures corrosion resistance and structural integrity, while a neoprene gasket offers effective weather sealing. The fixture is designed for operational reliability in extreme temperatures ranging from -55°C to +55°C, making it suitable for installations in diverse climates and regions.
The obstruction light’s physical dimensions include a flash head height of 7.5 inches (19.05 cm), length of 10.75 inches (27.31 cm), and width of 5.25 inches (13.31 cm), with a total weight of 10 lbs (4.54 kg). Its wind load footprint is minimal, measuring just 0.2 square feet, helping maintain structural stability even under high wind conditions. Installation and maintenance are straightforward and do not require specialized tools, adding to the fixture’s practicality for field deployment. Hub size options start at 0.75 inches, with enlarger adapters available for 1-inch and 1.25-inch mounting configurations.
Backed by a five-year limited warranty, this obstruction light provides a reliable, cost-effective solution for meeting FAA compliance in low-intensity, red-light aviation marking applications, especially in areas where solar power or LED options are not suitable.
