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.

Questions about this item
How many hours will the 40W halogen lamp run before it reaches its rated life limit?
The lamp is rated for 1500 operating hours under normal airfield service conditions.
What heat or noise should I expect when the 40W halogen bulb runs continuously all day?
A 40W halogen capsule generates significant heat during extended operation and requires adequate fixture ventilation; it operates silently with no moving parts.
Which power supply must I already have to operate this 6.6A MR11 airfield bulb?
A 6.6A constant-current regulator with leads compatible with the female round base is required for correct operation.
