OSRAM HLX 64623 100 W 12 V Halogen

The OSRAM HLX 64623 is a 100 watt, 12 volt halogen bulb with a GY6.35 two-pin base. It delivers 2800 lumens and a colour rendering index of 100 for accurate colour reproduction. The lamp suits dental, ophthalmic, microscope, projector, scientific and studio equipment requiring a T4 single-ended source. Buyers needing a different base type or voltage should look elsewhere.

XENOPHOT HLX sustained output

The bulb uses xenon gas instead of krypton, giving a 10 percent higher luminous flux at the same power draw. Rated life is 2000 hours under continuous operation. The C-Bar-6 filament and clear finish maintain stable output throughout the rated lifespan. Installations demanding uninterrupted high-intensity light for extended periods will see consistent performance.

Replaces legacy GY6.35 halogen lamps

This model directly replaces existing GY6.35 100 watt 12 volt halogen bulbs in compatible fixtures. The upgrade is worthwhile when the application benefits from the xenon fill's increased flux and the 100 CRI. It is not a substitute for LED modules or discharge lamps that require different power supplies or optical designs.

Questions about this item

How much heat does the 100 W halogen filament produce during continuous operation?

At 100 watts the lamp converts most input power into heat; the compact T4 envelope measuring 1.716 inches long and .453 inches in diameter will become very hot, so ensure the fixture allows free airflow and keep flammable materials away.

What fixture or power supply must I already have to run this 12 V GY6.35 bulb?

You need a socket that accepts the GY6.35 two-pin base with 6.35 mm pin spacing and a 12 volt AC or DC source capable of delivering 100 watts; the bulb cannot operate directly from mains voltage.

Will this 2800 lumen xenon-filled halogen work in my older microscope illuminator designed for krypton lamps?

Yes — the 64623 XENOPHOT version fits the same GY6.35 base and 12 V supply while providing about 10 % more light output at the same 100 W draw, so it serves as a direct replacement in legacy scientific or optical instruments.
