SATCO Lighting S11239 5W G9 LED, Clear, 5000K, T4 Shape, 120V

The Satco S11239 is an enclosed rated lamp, so it can go in a sealed or covered fixture, which is where most G9 sockets actually live (flush mounts, wall sconces, small chandeliers with glass shades). It is rated for damp locations and indoor use, so a covered porch or bath vanity is fine, but not a wet exposed location. Many G9 LEDs are not enclosure rated and fail early in those fixtures.

No, and this is the most common mistake on a G9 relamp. The S11239 is 5000K, a cool white daylight tone. Halogen G9 capsules read around 2700K to 3000K warm white, so putting this in one sconce of a matched run will make it visibly blue next to the rest. Use 5000K where you want it uniformly: a garage, a utility room, a laundry, a stairwell, or relamp a whole space at once. For guest rooms, lobbies, and dining fixtures, order a warmer G9 instead. CRI is 80, standard for general commercial lighting but not what you want over merchandise or artwork.

The lamp is dimmable on 120V, 60Hz line voltage. What it is not is a guaranteed match for an old halogen dimmer. A magnetic or leading edge dimmer sized for a 40W halogen load expects far more current than 0.042 amps per lamp, and a fixture of five or six of these draws under a quarter amp total, which often falls below the dimmer's minimum load and shows up as flicker, drop out at the low end, or a lamp that will not strike. If you are converting a dimmed circuit, plan on an LED rated dimmer with a low minimum load.

It depends how much you mind seeing the diodes. The S11239 is a clear T4 capsule, so the LED elements inside are visible when the lamp is exposed, the same way a clear halogen capsule shows its filament. In a fixture with a shade, a frosted glass, or a lamp that sits down inside the housing, that is a non issue and the clear body gives you the sparkle through cut glass that a frosted lamp kills. In a fully open chandelier at eye level, look at a frosted G9 instead. The 300 degree beam spread means it throws light nearly all the way around either way.

Satco rates the S11239 at 25,000 average hours. Halogen G9 capsules typically run 2,000 to 3,000 hours, which is why a hotel corridor or a lobby chandelier eats a case of them a year. At 25,000 hours a fixture burning 12 hours a day goes roughly five and a half years between relamps. For a property manager or MRO buyer, that is the whole argument: the labor of getting a lift under a chandelier costs more than the lamps do.

Yes. The S11239 is Title 24 compliant, which is what a California inspector wants to see on high efficacy lighting in a dwelling unit, and it is FCC compliant for RF emissions. That matters on multi-family and hospitality work in California where the G9 sconces have to count as high efficacy sources.

Damp locations only. The lamp carries a damp location rating and is designated for indoor use, so a covered entry, a bathroom vanity, or a laundry is within its rating. Direct rain, an open soffit that takes blowing water, or the inside of a shower enclosure calls for a wet location rated lamp and fixture instead.

No. The S11239 is not a three way lamp, so in a three way circuit it will simply be on or off with no step levels. G9 is a pin base anyway and three way switching runs through Edison medium bases, so if you have a three way socket you are looking at the wrong base entirely. For level control on a G9 fixture, dim it instead, since this lamp is dimmable.

The base is ceramic rather than plastic, which is what you want in a G9 socket buried in a small enclosed housing where heat has nowhere to go. Combined with the enclosed rated construction, that is the pairing that keeps a G9 LED from cooking itself in a flush mount or a wall sconce.

Fixed at 5000K. The S11239 is not a CCT selectable lamp, so there is no switch on the base to move it to 3000K or 4000K. If you are standardizing a building and want one SKU that covers warm and cool spaces, this is not that lamp, you order the color temperature you need per space.
