The Obelux medium-intensity stand-alone obstruction light, featuring a 20,000 candela white output and a 100 candela red W, rot ES flashing signal, is specifically designed for wind turbines in the German market. This advanced lighting solution incorporates essential features such as fault monitoring, an integrated photocell for automatic day/night operation, and optional GPS synchronization to ensure precise flash timing. Additional connectivity options include serial RS-485 and Ethernet interfaces, allowing seamless integration into complex aviation lighting control systems.
Optically, the light emits aviation-grade white and red colors, with a full 360° horizontal beam ensuring visibility from all directions. The red signal complies with the W, rot ES specification featuring a vertical beam pattern with flashing functionality designed to meet German regulatory requirements. Infrared output is not included in this model. The white light delivers a powerful 20,000 candela effective intensity, while the red flashing light provides 100 candela effective output.
This medium-intensity light is certified to meet international and national standards. It complies with ICAO International Standards and Recommended Practices as outlined in Aerodromes Annex 14, Volume 1, 7th Edition (July 2016), specifically Chapter 6 for Medium-intensity Type A lights. Additional certifications include German national regulations BMVBW LS 11/60.01.87-01/5 Va 02 (September 2002) and publication in the Bundesanzeiger (Federal Gazette) on September 1, 2015, confirming its compliance with the W, rot ES specifications required in Germany.
The unit is built on reliable LED technology, delivering effective white flashing light at 20,000 cd and red W, rot flashing at 100 cd. It is designed to operate effectively in offshore environments, ensuring robustness in harsh conditions. The luminous output levels are adjustable across three settings—10%, 30%, and 100%—allowing for flexible operation depending on visibility needs and energy consumption requirements. Incorporated photocell and fault monitoring functions contribute to safe and dependable operation by automating light activation and providing alerts in case of malfunctions.
Electrically, the obstruction light supports a wide AC operating voltage range of 90 to 265 VAC. It offers selectable flash rates of 20, 30, 40, or 60 flashes per minute to comply with diverse regulatory and operational demands. The unit meets EMC emission and immunity standards EN 61000-6-4 and EN 61000-6-2, ensuring minimal interference with other electronic equipment and stable operation in electromagnetic environments. Typical power consumption is 19 watts during daytime operation with white flashing at 40 FPM, while nighttime operation with the red W, rot ES flashing signal uses less than 10 watts. The flash pulse length remains consistent at 100 milliseconds for both day and twilight modes.
For installation, recommended outdoor cables include 3x1.5mm² or 3x2.5mm² for power (L-N-PE), CAT 6 for data transmission, and options for alarm signaling with CAT 6 or additional power and alarm cables (6x1.5mm² or 6x2.5mm²). The light’s terminals support distributing power and data to additional light heads, which requires using a 6-core cable to ensure proper connectivity for multi-light setups.
Mechanically, the light is housed in a painted marine-grade aluminum enclosure (C5MHigh) with a durable glass cover, designed for longevity and resistance to harsh weather conditions. It features an IP66 ingress protection rating, safeguarding the fixture against dust and powerful water jets. The device is engineered to operate reliably within a broad temperature range from -40 °C to +55 °C, accommodating both extreme cold and hot climates. Mounting is facilitated via a standard 240 x 240 mm base with 17 mm diameter holes, ensuring compatibility with common structural mounting arrangements.
In summary, the Obelux medium-intensity stand-alone 20,000cd white and 100cd red W, rot ES flashing obstruction light is a highly reliable, regulation-compliant solution tailored to the needs of German wind turbine operators. Its combination of robust construction, advanced features, and flexible operation makes it an ideal choice for safe and efficient marking of tall structures in demanding environments.
