Halogen Airfield Bulb for 6.6A Circuits

This OSRAM tungsten halogen lamp delivers 45 watts at 6.6 amps with a colour rendering index of 100. It is built for aircraft and airfield lighting systems that require precise current-controlled operation.

Verify Connector and Power Match

Confirm the fixture uses a female round connector designated 64337B before ordering. The supply must provide a 6.6A constant-current circuit; the lamp is not compatible with standard voltage-fed sockets or flat-connector variants such as 64337A or 64337C.

Fits Series Circuit Fixtures

The female round leads plug directly into series-wired airfield circuits, freeing the installer from voltage-drop calculations across long cable runs. Rated life is 1500 hours; IRC versions in the same series offer 3000 hours if longer intervals between replacements are needed.

Questions about this item

Does the 58908 bulb come with a socket or fixture, or is only the halogen lamp supplied?

Only the halogen lamp with its female round connector leads is supplied; any MR16 fixture or series circuit socket must be purchased separately.

How do I choose between the 45 W 1500-hour version and the 48 W 3000-hour IRC version when both have female round connectors?

Select 58908 for 45 W and 1500 hours; select 58906 for 48 W IRC and 3000 hours — both use the 64337B female round connector.

What does the 6.6 A current rating mean when the bulb is installed in a real airfield series circuit?

The 6.6 A rating matches the constant-current output of airfield series regulators, so the lamp receives exactly 45 W and achieves its 1500-hour life when the circuit runs at 6.6 A.
