The PRO APF TP312 MIRL is a versatile LED lighting fixture designed for use as a medium intensity runway edge light, medium intensity threshold/end light, and displaced threshold light. It is engineered to meet the demanding requirements of modern airfield lighting, providing reliable and efficient illumination for safe aircraft operations during landing, takeoff, and taxiing.
This fixture complies with Canadian aviation standards, specifically Canada TP312 5th Edition section 5.3.22.9, along with Appendix 5B Table 5B-1 and Appendix A sections 1.3 and 1.4, ensuring its suitability for regulated airfield environments. Its design integrates WaveTrac™ technology, which reduces power consumption by up to 60% compared to traditional incandescent lights, contributing significantly to energy savings and operational efficiency.
The TP312 MIRL supports the universal power supply system used across PRO APF in-pavement lighting fixtures, allowing for streamlined inventory management and simplified maintenance. It operates reliably within a temperature range of -40°C to +55°C, making it suitable for use in a variety of climates and environmental conditions.
Designed with ease of installation and maintenance in mind, the fixture features a removable nut that secures the glass dome to the housing, providing quick access to the power supply and LED optical assembly. Built-in leveling bosses accommodate a standard circular bubble level, and the unit employs a three-screw leveling system with hex head bolts to ensure precise alignment during installation.
The PRO APF TP312 MIRL is available in multiple installed heights—14 inches (350 mm), 24 inches (607 mm), and 30 inches (759 mm)—to meet various operational requirements. It is compatible with both 1.5-inch and 2-inch baseplate hubs, offering flexibility in mounting configurations.
Utilizing long-life LED technology, the fixture boasts a projected operating life exceeding 50,000 hours at 6.6 amps, ensuring long-term reliability and reduced replacement frequency. Its housing is constructed from highly durable cast aluminum painted yellow for enhanced corrosion resistance and visibility.
The light supports up to five-step constant current operation and includes options for an external power cord and grounding to ensure TP312 compatibility. An optional energy-efficient arctic kit is available, which applies a filament directly to the glass dome to minimize energy losses in cold environments.
The PRO APF TP312 features a frangible coupling with an integral fluid barrier designed to prevent ambient moisture and precipitation from entering the base, preserving the fixture’s internal components. Both the LED and electronics are housed within an IP67-rated assembly, offering strong protection against dust and water ingress.
Additionally, the typical fixture exhibits a low in-rush voltage of 1.5 volts, contributing to its overall electrical efficiency and reliability. Together, these features make the PRO APF TP312 MIRL a robust, energy-efficient, and easy-to-maintain solution for medium intensity runway edge and threshold lighting needs.
