Compact Halogen for Low-Voltage Fixtures

This Ushio JC halogen bulb delivers 3300 K light from a 30 W, 6 V capsule. It fits G4 sockets found in desk lamps, hanging fixtures, microscopes and medical instruments. The 1.18 inch length keeps it inside tight housings. Rated life is 50 hours.

G4 Pin Base and Tiny Envelope

The two-pin G4 base plugs directly into low-voltage sockets without adapters. Its 1.18 inch overall length allows installation in slender projector or ophthalmic housings. The miniature envelope handles the heat of a 30 W load in confined spaces. No additional mounting hardware is required.

Heat, Noise and Power in Use

At 30 W and 6 V the lamp draws modest current while producing concentrated halogen output. The small capsule reaches operating temperature quickly, so fixtures should allow airflow around the quartz. No fan or moving parts means silent operation. The 50 hour rating reflects the high intensity in a compact form.

Questions about this item

What does the G4 base limit in practice?

The G4 base restricts use to 6 V low-voltage fixtures; the lamp draws 30 W and cannot be connected to mains voltage.

What physical space does the 1.18 inch length require?

The lamp measures 1.18 inches overall, so the socket and shade must accommodate that exact length without forcing the glass against any surface.

How is the halogen capsule installed, and what step is often missed?

Insert the bi-pin G4 base firmly until seated, but never touch the quartz envelope with bare fingers — skin oils create hot spots that shorten the 50 hour rated life.
