Airfield halogen bulb for precision lighting

The SYLVANIA 58889 is a 40-watt MR11 halogen lamp designed for airfield and airport fixtures. It operates on a 6.6-ampere current-controlled circuit and uses leads with a female round base for direct connection. The multifaceted reflector produces a focused beam suitable for runway and taxiway guidance systems.

Fits constant-current series circuits

This bulb installs directly into existing airfield lighting circuits that supply 6.6 amperes, requiring no separate ballast or driver. Its compact MR11 form factor allows installation in a wide range of fixture housings where space is limited. The lamp operates in any orientation, giving installers flexibility when aiming the beam.

Sustained output with high colour fidelity

Under continuous operation the lamp maintains a Colour Rendering Index of 100, ensuring accurate colour discrimination for critical visual tasks. Rated life is 1500 hours at the specified 40-watt load. The halogen fill sustains lumen output over the service interval better than gas-filled equivalents.
