Sylvania 58846 Airfield Halogen Lamp

The Sylvania 58846 is a 45 watt tungsten halogen incandescent bulb designed for airfield lighting systems that operate on 6.6 ampere constant-current circuits. It uses a T3.5 envelope with a GZ9.5 bi-pin prefocus base and produces a 3200 K clear output suited to aviation approach and runway fixtures.

EXM Current-Controlled Operation

The EXM designation confirms the lamp is built for series current-controlled circuits rather than constant-voltage supplies, so it must be installed in a compatible airfield lighting circuit with the correct isolation transformer. The single-ended design and prefocus base ensure precise filament alignment within the optical system of the fixture.

Questions about this item

How often will the 45 W 6.6 A tungsten halogen lamp need replacement?

The lamp is rated for typical airfield service life; replacement is required when light output drops below the 3200 K specification or the filament fails.

What is the first limit reached during continuous operation?

The 45 watt power draw and 6.6 A current set the thermal limit; sustained use will hit filament temperature limits before any other constraint.
