SATCO Lighting S21208 4.5W G16.5 LED, White, Candelabra Base, 90 CRI, 4000K, 120V

Yes. The S21208 is an enclosed rated lamp, so it can go in sealed or fully enclosed fixtures where heat build-up would shorten the life of a non-rated LED. It also carries a Wet location rating and is listed for indoor or outdoor use, which covers covered porch fixtures, sconces and exterior lanterns.

It replaces a 40W incandescent candelabra lamp while drawing 4.5W, putting out 350 lumens. For a property manager relamping a lobby chandelier or corridor sconces, that's roughly a 35W reduction per socket with comparable light output.

The lamp is dimmable. It is not a three-way lamp, so it will not step through levels in a three-way socket. With any LED retrofit on an older incandescent dimmer, you want a dimmer rated for LED loads and enough lamps on the circuit to meet the dimmer's minimum load, otherwise you get flicker or drop-out at the bottom of the range.

4000K is a neutral white, cooler and crisper than the 2700K warm glow most people expect from a decorative chandelier. It suits commercial corridors, lobbies, back-of-house and task areas where you want clean white light. For hospitality or residential dining where a warm candlelit look is the point, pick a 2700K lamp instead. The S21208 is fixed at 4000K, not CCT selectable.

90 CRI, which is the threshold most retail, healthcare and hospitality specs call for when skin tones, finishes or merchandise color have to look right. Standard LED lamps often sit at 80 CRI, so this is a step up for spaces where the light quality is visible to guests or customers.

Yes, it is Title 24 compliant, which matters for California projects where lighting has to meet the state energy code. It is also FCC compliant. It is not DLC listed, so if your utility rebate program requires a DLC qualified product, this lamp will not qualify for that particular incentive.

It is the white finish version, so the G16.5 glass is opaque rather than clear. The LED filaments inside are diffused instead of visible as bright lines, which is what you want when the lamp sits exposed in an open chandelier or sconce and glare is a concern. The beam spread is 320 degrees, so it throws light nearly all the way around.

Burning position is universal, so the S21208 can be mounted base up, base down or horizontal without affecting performance. That matters for vanity bars and sconces where sockets point sideways, and for pendant fixtures where the lamp hangs base up.

Rated at 15,000 average hours. On a fixture burning about 12 hours a day that works out to roughly three and a half years between changes, which is the argument for LED in high-ceiling chandeliers, stairwell sconces and any location where getting a lift or ladder in is the real cost of a relamp.

Glass body with a nickel plated aluminum base. The nickel plating is what resists corrosion and seizing in the socket, which is the usual failure point on exterior lanterns and covered entry fixtures. Combined with the wet location rating, that makes it a reasonable choice for outdoor decorative sockets.
