LED G4, G9 & B6 Capsule Bulbs

Bi-pin capsule LED in G4 at 1.8W and 2.5W on 12V, and G9 at 4.5W on 120V, in 3000K soft white and 6000K super daylight with dimmable models, alongside a 4W B6 candle.

Pin spacing and voltage are the compatibility specifications and both are explicit per SKU. G4 and G9 are not interchangeable despite looking alike, and a 12V capsule in a line-voltage fixture fails on first use.

Capsules feed decorative chandeliers, under-cabinet fittings and small pendants — fixtures where the lamp is often visible. Halogen equivalents are in T3 JC and T4 JC capsules.
