SATCO Lighting S11235 5W, JCD LED, Clear, 4000K, G9 Base, 120V

That is the direct swap it is built for. The S11235 draws 5 watts and puts out 550 lumens, rated as a 40W incandescent equivalent, on the same G9 double loop base you pull the halogen capsule out of. Line voltage 120V, so no transformer involved. The difference you will see is color: this one is 4000K neutral white, noticeably cooler than the warm 2700K-ish light a halogen capsule gives.

Yes. The S11235 is an enclosed rated lamp, so sealed sconces, flush-mount ceiling pans, and closed glass shades are all fair game. That matters with G9 sockets in particular, since most of them sit inside small enclosed decorative housings where a non-enclosed-rated LED cooks itself and dies early. It is also damp location rated for indoor use, which covers a bath or covered entry ceiling, but it is not a wet location lamp.

The lamp is dimmable at 120V, 60Hz. Worth knowing before you order a case: a 5 watt load is tiny, and an older dimmer designed for incandescent halogen loads often has a minimum load it cannot drop below, so a single G9 on a legacy dimmer can flicker or refuse to start. Multi-lamp chandeliers and fixtures with several of these are usually fine. On a one-lamp circuit, plan on an LED-rated dimmer.

Clear housing with a clear plastic lens means you see the LED chips directly, same as you saw the halogen filament before. In an open-arm chandelier or an exposed candelabra fixture that reads as sparkle, which some people want and some find glarey. Behind a shade, a diffuser, or a frosted glass globe, clear is the better pick because you get more light through with no visible source. If the socket is fully exposed at eye level and glare is a concern, go frosted instead.

Burning position is universal, so base-up, base-down, or horizontal all work. That covers the awkward mounting you get in G9 sockets: wall sconces firing sideways, pendant sockets pointing down, and cove or under-cabinet housings where the lamp lies flat. With a 300 degree beam spread it throws light nearly all the way around, so orientation does not cut your output either.

4000K is neutral white, the commercial standard for corridors, lobbies, restrooms, and back-of-house. It will not match 2700K or 3000K warm-white lamps in the same room, and mixing them in one fixture is obvious. This lamp is not CCT selectable, so what you order is what you get. For a fleet standardization across a property, decide on one temperature and order the whole run at it.

Yes, the S11235 is Title 24 compliant, so it can go into California residential and commercial lighting scopes where that is called out on the drawings. It is also FCC compliant. Note it is not DLC listed, so if a utility rebate program you are chasing requires a DLC qualified product, this lamp will not qualify for it.

The base material is ceramic, which holds up to the heat that builds in the tight, often enclosed housings G9 sockets live in and resists deforming in the socket the way a plastic base can. The lamp body is a T4 shape, the same slim tube profile as the halogen JCD capsule it replaces, so it clears the small glass shades and shallow sconce backplates those sockets were designed around.

No. The S11235 is a single-output 5W lamp at 550 lumens, not three-way. G9 sockets do not support three-way switching in any case. If you need adjustable output on this fixture, dim it, since the lamp is dimmable.
