OSRAM 64423 Halogen G4 12V 15W

This OSRAM Halostar PRO halogen lamp uses a G4 bi-pin base and runs on 12 volts. It draws 15 watts while delivering 220 lumens of warm white light at 3000K. The bulb is aimed at homeowners and lighting installers who need a direct retrofit for low-voltage accent fixtures.

G4 bi-pin base and 12 V operation

The G4 bi-pin base and 12-volt rating are the only specifications that determine whether this lamp fits the socket and matches the transformer. If the fixture uses a different pin spacing or a mains-voltage supply, this bulb will not work. No other dimension or electrical parameter overrides this requirement.

Dimmable with UV protection

The lamp is fully dimmable, allowing light levels to be adjusted without changing the fixture. Its built-in UV filter helps prevent fading of illuminated objects such as artwork or fabrics. A rated life of 4000 hours reduces the frequency of replacements in hard-to-reach locations.

Questions about this item

What does the 220-lumen output mean for brightness in a desk or cabinet fixture?

It provides a warm 3000K accent light equivalent to a traditional 20W halogen while drawing only 15W, rendering colours at 90-100Ra.

How does the G4 bi-pin base limit the power supply I can use?

The G4 base requires a 12V supply; you must pair it with a compatible low-voltage transformer or driver, not mains voltage.

What clearance does the capsule need behind the mounting surface?

The compact G4 capsule fits shallow fittings, but allow enough depth for the bi-pin holder and any transformer wiring.
