SATCO Lighting S21207 4.5W G16.5 LED, White, Candelabra Base, 90 CRI, 2700K, 120V

Yes, the S21207 carries a wet location rating and is listed for indoor or outdoor use, so it can go in a covered porch fixture, a post lantern, or a shower-area vanity. It is also enclosed rated, which matters on the same jobs: sealed outdoor lanterns and closed globes trap heat and shorten the life of lamps not built for them.

90 CRI, which clears the 90-plus threshold hospitality and retail specs commonly call for and renders skin tones and finishes far more accurately than a typical 80 CRI lamp. It is also Title 24 compliant, which matters on California projects where lighting has to meet the state energy code.

Dimmable, yes. The practical catch is the load: at 4.5 watts a single lamp draws almost nothing, and older forward-phase dimmers built for incandescent loads often need a minimum wattage to run smoothly. A chandelier with six or more of these on one dimmer is the safer application than a single lamp on a leftover incandescent dimmer.

At 2700K the S21207 puts out the same warm white as a standard incandescent lamp, so it will blend with untouched incandescent fixtures in the same room. Note the finish: this is the white version, meaning a diffused glass envelope that hides the filaments and spreads light evenly, not the see-through clear look. Mixing white and clear versions in one open chandelier will read as a mismatch even though the color temperature is identical.

Burning position is universal, so the S21207 runs base-up in a flush ceiling fixture, base-down in a chandelier arm, or horizontal in a sconce with no effect on rated life. That rating is 15,000 average hours, which at roughly 4 hours a night in a residential fixture is about 10 years before a maintenance call.

No on both counts. The S21207 is a single-output lamp: it is not three-way, so in a 3-way socket it will run at one level only, and it is not CCT selectable, so 2700K warm white is fixed with no field switch to 3000K or 4000K. If a facility standard calls for field-selectable color temperature, this is the wrong lamp to standardize on.

Order by Satco part number S21207. That number covers the 4.5 watt G16.5 white finish at 2700K with a candelabra base on 120 volt, and white is the only finish it comes in, so there is no second option to specify. Satco publishes separate numbers for clear finish and other color temperatures in this shape, so the part number is what pins down the version.

Not one for one. The S21207 is built to match a 40 watt incandescent at 350 lumens, so swapping it into sockets currently running 60 watt lamps drops roughly a third of the light per socket. In a multi-lamp chandelier the combined output usually still reads fine, but on a two-lamp sconce or a single pendant the room will be noticeably dimmer. Step up to a higher-lumen candelabra lamp where the 60 watt level has to be held.

LED filament construction, with a glass envelope and a nickel plated aluminum base. It is the format that mimics an incandescent filament lamp rather than a plastic-bodied LED with a heat sink collar, so it looks correct in an exposed decorative socket. The white glass diffuses the filaments instead of showing them.
