Replacement Halogen Light Bulb for Osram 64251 HLX Slit Lamp and Microscope Illumination - 6 Volts, 20 Watts, PG22 Base

Replacement for Osram 64251 HLX, this 6 volt, 20 watt halogen light bulb is the low-voltage projection lamp used in ophthalmic slit lamps, laboratory microscopes, and fiber optic illuminators. Also cataloged under Osram order code 54021, it uses a PG22 prefocus two-pin base that seats the filament in a fixed optical position, so the beam lands exactly where the instrument expects it without realignment.

• Instant on with nearly constant light output across the full 100 hour rated life
• Dimmable on compatible low-voltage controls for adjustable illumination intensity
