Satco Lighting S21837 – Frequently Asked Questions
1) How bright is a 5.5 watt B11 LED, and what incandescent bulb does it replace?
The Satco S21837 puts out 500 lumens on 5.5 watts. That output lands it in the range of a 40 watt incandescent candelabra-shape lamp, so it is a straight brightness swap for a 40W B11 while drawing a fraction of the power.
2) What is a B11 bulb shape and where is it normally used?
B11 is the small torpedo or candle shape, about the diameter of a finger with a tapered tip. It is what goes in chandeliers, wall sconces, bathroom vanity bars, and decorative pendants. The Satco S21837 pairs that candle shape with a medium screw base rather than the smaller candelabra base, so check which socket size your fixture actually has before ordering.
3) What color light does the Satco S21837 give off, and will it match the rest of my fixtures?
It is 2700K, the warm white tone that reads the same as a traditional incandescent. If the other lamps in your chandelier, sconces, or hallway fixtures are standard soft white incandescents or 2700K LEDs, this will blend. It will look noticeably yellower next to 3000K or 4000K lamps.
4) Is the Satco B11 bulb clear or frosted, and does that matter for an exposed fixture?
Clear glass. In an open chandelier, wall sconce, or vanity fixture where the bulb is visible, the clear envelope shows the filament-style look and throws sharper sparkle through cut glass or crystal. If you want the light source softened and glare cut down, a frosted B11 is the better pick.
5) How many bulbs come in a Satco S21837 order?
The S21837 ships as a 2-pack. Property managers relamping a multi-light chandelier or a run of sconces should count sockets and order accordingly, since one order covers two of them.
6) I need the exact Satco part number for a candle-shape clear LED in warm white.
That is Satco MPN S21837: 5.5W B11 LED, clear, medium base, 2700K, 500 lumens, 120V, sold two to a pack.
