Satco Lighting S21289 – Frequently Asked Questions
1) Can I use this 4W B11 LED in an enclosed fixture or an outdoor wet location?
Yes on both. The S21289 is an enclosed rated lamp, so sealed ceiling fixtures and closed globes are fine, and it carries a wet location rating for indoor or outdoor use. That covers covered porch fixtures, exterior sconces, and post lanterns. Burning position is universal, so base up, base down, or horizontal all work.
2) What incandescent bulb does this 4 watt LED replace, and how bright is it?
It replaces a 40 watt incandescent candle bulb, putting out 350 lumens on 4 watts at 120 volts. Current draw is 0.033A, so a circuit or fixture that was carrying a handful of 40W lamps has a lot of headroom once you swap.
3) Is the Satco S21289 dimmable on existing wall dimmers?
Dimmable, yes, on 120V 60Hz line voltage. It is not a three-way lamp, so it will not step through levels in a three-way socket. It also is not color-temperature selectable, it is fixed at 4000K.
4) Is 4000K too cool for a chandelier or dining area?
4000K is a neutral white, noticeably cooler and crisper than the warm yellow of a 2700K incandescent candle. For lobbies, corridors, stairwells, offices, and commercial common areas it reads clean. For a residential dining room where tenants expect warm light, pick a 2700K or 3000K B11 instead. The 90 CRI rendering is high either way, so colors and finishes look accurate under it.
5) Will this frosted B11 throw light all the way around in an open chandelier?
Beam spread is 300 degrees, so it lights nearly the full sphere rather than projecting forward like a reflector lamp. Combined with the frost finish that diffuses the LED filaments, it works in exposed candelabra-style fixtures where the bulb is seen from every side.
6) Does the Satco S21289 meet California Title 24 for a lighting retrofit?
Title 24 compliant, yes, and FCC compliant. It is not DLC listed, so if a utility rebate program you are filing under requires a DLC-qualified product, this lamp will not satisfy that requirement.
7) How long does this LED candle bulb last before maintenance has to relamp?
Rated average life is 15,000 hours. On a common area fixture running roughly 12 hours a day that is around three and a half years between changes, which is the main argument for swapping out 40W incandescent candles in hard-to-reach sconces and chandeliers.
8) What is the bulb actually made of, and will it hold up in an exterior fixture?
Glass envelope with a nickel plated aluminum base. Nickel plating on the screw base resists corrosion better than plain brass in damp sockets, which matters for the wet-location exterior fixtures this lamp is rated for.
