Satco Lighting S21278 – Frequently Asked Questions
1) What incandescent candelabra bulb does a 5.5W B11 LED replace?
At 500 lumens, the S21278 sits in the range of a 40 watt incandescent candelabra lamp while drawing 5.5 watts. For property managers relamping chandeliers and sconces, that is roughly a 7x cut in connected load per socket.
2) Will this LED match the warm color of the incandescent bulbs already in my fixtures?
Closely. The S21278 is 2700K, the same warm white as a standard incandescent, and it carries a 90+ CRI rating so skin tones, wood, and fabric render accurately. That 90 CRI level is what hospitality and residential lobby specs usually call for.
3) Is the Satco S21278 frosted or clear?
Frosted. The frost finish diffuses the LED filament glare, which is what you want in open chandeliers, wall sconces, and exposed candelabra fixtures where the lamp is in the line of sight. If you want a visible filament look, this is not the lamp.
4) What is the Satco S21278 bulb made of?
Glass envelope with a nickel plated aluminum base. The lamp weighs 0.04 lb, so it puts almost no load on delicate chandelier arms or candle sleeves.
5) Where can I get the full photometric spec sheet for Satco S21278?
