The CASA (Australia) Low-Intensity Stand-alone Obstruction Light series from Obelux is engineered using advanced LED technology to provide reliable, energy-efficient marking for tall structures such as wind turbines, chimneys, masts, and towers. These lights produce a 100 candela red light that can operate in fixed or flashing modes. A key feature of the design is the incorporation of a photocell for automatic day/night switching, as well as fault monitoring and switching capabilities built directly into the light fixture. The product is also fully compatible with Night Vision Goggles (NVG) due to its integrated infrared capabilities, enhancing its suitability for aviation safety applications. For expanded control and monitoring, the lights can optionally be connected to the Obelux aviation lighting system via Modbus communication protocols.
Optically, the CASA low-intensity lights deliver a uniform 360-degree horizontal beam with a vertical beam spread of 10 degrees. The vertical light distribution guarantees a minimum intensity of 100 cd between +6° and +10° above the horizontal plane, while maintaining at least 10 cd at all elevation angles ranging from -3° to +90°. This ensures clear visibility and effective marking of obstacles regardless of viewing angle.
Designed to comply with the Civil Aviation Safety Authority (CASA) of Australia’s Manual of Standards, Part 139, Chapter 9.4.6, these lights meet stringent requirements for low-intensity obstacle lighting. The system supports both standalone operation—with incorporated alarm signaling—and Modbus communication, allowing for flexible integration into broader aviation safety infrastructure. The product offers GPS synchronization to ensure precise timing and coordination with other lights in the system.
Electrically, the CASA series supports a wide voltage range to accommodate various power sources. AC models operate from 100 to 250 VAC at 50-60 Hz, while DC models cover 10 to 60 VDC. The lights feature robust Type II overvoltage protection and isolated RS-485 communication interfaces for fault monitoring and remote control. Connection points can be safeguarded with fuses or circuit breakers rated at 6A or 10A (C curve). Additionally, an alarm relay is built-in with ratings of 250 VAC at 8A and 50 VDC at 1A for external fault indication.
Further enhancements include low power consumption for extended operational cost savings and thermostatically controlled heating elements. DC models come equipped with smart heaters and battery-powered operation options, including deep discharge protection to maintain battery health and longevity. The lights offer over 10 years of maintenance-free operation and come with a 5-year warranty, with an optional extension to 10 years, representing one of the longest warranties in the industry for this product category.
