OSRAM SYLVANIA 64337C IRC 48W 6.6A Airfield Halogen Bulb

Purpose-built airfield illumination

The OSRAM 64337C IRC halogen bulb delivers 48 W at 6.6 A for runway and taxiway lighting systems. Its MR16 form factor fits dedicated airfield fixtures that require precise photometric control. The lamp is designed for aviation ground-lighting circuits where constant-current regulators supply the rated amperage.

Constant-current leads with male connector

Factory-fitted leads terminate in a male connector that matches the series-circuit sockets used on airfield lighting circuits. This wiring method eliminates screw-terminal work on site and maintains the 6.6 A loop integrity required by aviation standards. The halogen capsule and IRC coating withstand the thermal cycling of daily dusk-to-dawn operation.

3 000-hour rated life at full output

At 48 W the bulb achieves a 3 000-hour service interval with a colour rendering index of 100, ensuring true-colour visibility for pilots and ground crews. The IRC infrared-reflective coating redirects heat back to the filament, sustaining lumen maintenance over the rated period. Buyers needing longer intervals or lower-current LED retrofit solutions will require a different technology.
