An Osram Halostar halogen capsule bulb, G4 base, 12V, 10W — a compact low-wattage capsule for under-cabinet lighting, display cases, and small 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.
