Satco Lighting S21831 – Frequently Asked Questions
1) What color light does the Satco S21831 B11 bulb give off?
5000K, which reads as a crisp daylight white rather than the warm yellow of a traditional incandescent candle lamp. If you are mixing it into a chandelier alongside 2700K lamps, the difference will be obvious, so plan on changing the whole fixture over.
2) How bright is a 5.5W candelabra LED, and what incandescent does it replace?
The S21831 puts out 500 lumens on 5.5 watts. That output sits in the range a 40 watt incandescent candelabra lamp produced, so it is a practical swap for 40W B11 decorative bulbs while drawing a fraction of the power.
3) Is the Satco S21831 clear or frosted glass?
Frosted. The frosted finish diffuses the light and hides the LED filament or diode array, which keeps glare down in open chandeliers and shade-less sconces where the lamp is visible. Clear versions of B11 lamps show the filament instead.
4) How many bulbs come in a Satco S21831 order?
Two. S21831 is sold as a 2-pack of the 5.5 watt frosted B11 candelabra lamp, so a multi-arm fixture will need several packs to relamp completely.
