Osram Halogen Capsule 12V 20W G4

An Osram Halostar halogen capsule bulb, G4 base, 12V, 20W — for under-cabinet lighting, display cases, and low-voltage decorative fittings.

Will this fit my fixture?

This is a 12V low-voltage bulb — check your existing fixture runs on 12V with a compatible transformer, not standard 230V mains. If your old bulb was a G4 halogen capsule, this is a direct swap once power is off.

Key Features

• G4 bi-pin base, compact capsule design
• 12V, 20W — higher output than the 10W capsule for the same family
• Warm White (~2800K), fully dimmable
