SATCO Lighting S21298 4W CA10 LED, Clear, Candelabra Base, 90 CRI, 4000K, 120V

Yes. The S21298 CA10 lamp is an enclosed rated lamp, so it can go in a sealed or fully enclosed fixture without voiding its rating. It also carries a Wet location rating and is rated for indoor or outdoor use, which covers covered porch fixtures, post lanterns and sconces that see weather.

4000K is a neutral white, closer to daylight than to candle glow. In a dining room or hospitality chandelier where guests expect a warm amber look, it will read noticeably cool. It suits corridors, lobbies, stairwells, offices and exterior sconces where you want crisp light and good color accuracy, which the 90 CRI rating supports. If you want the warm look, choose a 2700K version of the CA10 filament lamp instead.

The S21298 is a dimmable lamp. Keep in mind that at 0.033 amps each, a chandelier full of them draws very little current, and legacy incandescent dimmers have a minimum load they need to see to behave. If you are retrofitting a dimmer that previously ran 40W incandescent candles, expect better results from an LED-rated dimmer.

Only if the rest are also 4000K. The S21298 is a fixed 4000K lamp, not CCT selectable, so you cannot field-adjust it to match a warmer or cooler group. For a property manager standardizing a fleet of fixtures, the practical move is to commit a whole space to 4000K rather than swapping one bulb in a chandelier, since a single neutral lamp beside 2700K lamps is obvious.

Burning position is universal, so it works base-up, base-down or horizontal. That matters for candelabra fixtures, which mount lamps every which way, and for wall sconces where the socket points sideways.

Yes, the S21298 is listed as Title 24 compliant, which is what a contractor needs when specifying residential lighting in California. It is also FCC compliant. It is not DLC listed, so it will not qualify for utility rebate programs that require DLC.

No. It is a 120V, 60Hz lamp only. Do not put it in a 277V commercial circuit or on 50Hz export power. For a 277V fixture you need a lamp rated for that voltage or a line-voltage change at the fixture.

It is an omnidirectional-style lamp with a 300 degree beam spread, which comes from the LED filament construction rather than a chip-on-board emitter. In a clear glass chandelier or an open lantern the filament stays visible from most angles, which is the point of a clear decorative candle lamp.

Rated life is 15,000 hours. Run roughly 12 hours a day in a hotel corridor or lobby chandelier, that is about three and a half years per lamp, so relamping cycles are far longer than with incandescent candles. For a big chandelier, replacing the whole set at once is usually less labor than chasing individual failures.

It is glass with a nickel plated aluminum base. Glass holds up better than plastic to UV and heat in an exterior lantern, and the lamp carries a wet location rating for that use. The tradeoff is that glass is breakable, so it is less suited to vandal-prone or vibration-heavy locations.

If color rendering matters in the space, yes. At 90 CRI the S21298 renders skin tones, wood, fabric and artwork much closer to true than typical 80 CRI decorative lamps. That is worth paying attention to in hospitality, retail, healthcare exam-adjacent areas and office lobbies. In a back-of-house stairwell it makes no practical difference.

It is not a three-way lamp. Installed in a three-way socket it will light at full output on the on positions that energize its contact, with no step levels. For stepped control you need either a three-way rated lamp or a dimmer, and the S21298 is dimmable.
