Aircraft Halogen Bulb 48W

The OSRAM 64337A IRC is a 48-watt halogen lamp rated for 6.6 amperes with an MR16 form factor. It uses female flat connectors for direct wiring into aircraft lighting circuits. The bulb delivers a colour rendering index of 100 for accurate colour discrimination. It is intended for aviation applications requiring this specific power and current rating.

Sustained Output 3000 Hours

The lamp maintains its rated output for a design life of 3000 hours under continuous operation. Infrared coating technology reflects heat back onto the filament to stabilise efficacy throughout the cycle. Light output does not degrade rapidly in the early period as seen with uncoated halogen types. Performance remains consistent until the rated endpoint is reached.

Female Connector Installation

Installation requires mating the female flat connectors securely to the matching male terminals in the fixture. Loose connections cause arcing and premature filament failure at 6.6A. The MR16 envelope is fragile; handle only by the base to avoid contaminating the quartz. Verify the circuit supplies exactly 6.6 amperes before energising.

Questions about this item

How much heat does the 48W halogen bulb produce when run continuously?

The 48-watt halogen lamp converts most input power into heat; ensure the fixture and wiring are rated for continuous 48W operation and provide adequate ventilation.

What voltage supply and connector type are required for the 6.6A MR16 bulb?

It needs a 6.6-ampere constant-current supply and accepts the female flat connectors shown on the leads.

Can the 64337 IRC-A bulb replace an older MR16 lamp in an existing aircraft fixture?

Yes, if the fixture delivers 6.6A and uses the same female flat connector; the 3000-hour rated life and CRI 100 output match standard MR16 requirements.
