Aviation Halogen Lamp 45 W 6.6 A

This halogen airfield lamp delivers 45 watts at 6.6 amps and is built for constant-current airfield circuits. It carries the 64337A designation with female flat connectors and a rated life of 1500 hours. The bulb is supplied new and intended for approach, threshold or taxiway lighting systems.

Constant Current Series Circuit Limits

The lamp operates on a 6.6 A series loop where every fixture sees the same current; a single open filament extinguishes the entire circuit unless a bypass device is fitted. Regulators must hold 6.6 A precisely because voltage varies with loop length and lamp count. No parallel-voltage connection is supported by this design.

Connector And Regulator Verification

Confirm that the airfield fixture accepts female flat connectors matching the 64337A base before ordering. Check that the constant-current regulator is calibrated for 6.6 A output and that the circuit’s total voltage drop stays within the regulator’s compliance range. This model does not fit round-connector or male-connector sockets.

Questions about this item

Should I pick the 45 W or the 48 W version of the 64337A bulb?

Choose 45 W for standard 6.6 A circuits; choose 48 W IRC models 59070 or 58905 if the fixture supports the higher wattage and you want 3000-hour life.

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

It means the bulb is designed for a 6.6 A constant-current loop; the 45 W rating is the power it will draw at that current.

How does the female flat connector on the 64337A limit interchangeability with other 64337 variants?

The 64337A uses female flat connectors, so it only fits sockets wired for that style; 64337B has female round connectors and 64337C uses male flat connectors.
