Osram 64322 EXL | 30W 6.6A | GZ9.5/GY9.5 Halogen Airfield Series Lamp

The Osram 64322 EXL is a precision-engineered tungsten halogen lamp designed specifically for airfield ground lighting (AGL). Operating as a current-controlled light source in 6.6A series circuits, it provides a stable and consistent 430-lumen output across its 1,500-hour rated life. This FAA and ICAO-approved lamp is built with vibration-resistant technology to withstand the mechanical stresses of runway and taxiway environments. Its specialized prefocus bi-pin base ensures perfect optical alignment, making it a critical component for runway edge, threshold, and approach lighting systems worldwide.

Critical Reliability for Airfield Safety

The Osram 64322 airfield lamp is manufactured on state-of-the-art equipment to ensure tight tolerances in filament positioning (LCL). This optical precision is vital for the performance of elevated and in-pavement airfield fixtures, where light beam intensity and direction are strictly regulated. Beyond its visible output, its IR radiation capabilities provide essential guidance for aircraft using instrument approach conditions in low-visibility environments.

• FAA & ICAO Compliant: Certified for use in primary airfield lighting circuits.
• Xenophot Technology: Optimized gas fill for high luminous efficacy and reduced tungsten evaporation.
• Mercury-Free: An environmentally responsible choice for large-scale infrastructure.
• Flicker-Free & Dimmable: Allows for step-controlled brightness adjustments required by air traffic control.
