Satco Lighting S8542 – Frequently Asked Questions
1) Will the Satco S8542 LED bulb work in a 3-way lamp socket with a 3-way switch?
Yes. The S8542 is a true 3-way A21 LED, so it steps through all three levels in a 3-way socket: 5W, 15W and 21W, putting out 600, 1600 and 2150 lumens. Drop it in a standard single-contact socket and you'll only get the low level, so keep it in fixtures with the 3-way (two-contact) medium base socket.
2) What incandescent 3-way bulb does the Satco S8542 replace?
It's the LED stand-in for the common 30/70/100W incandescent 3-way. The S8542 draws 5W, 15W and 21W while delivering 600, 1600 and 2150 lumens, so the top step is brighter than a 100W incandescent (about 1600 lumens) at roughly a fifth of the load. Base and shape are the same A21 medium base an incandescent 3-way uses, so no socket change is needed.
3) Is 2700K going to match the incandescent 3-way bulbs already in my building's table lamps?
Yes, 2700K is the warm white that reads closest to a standard incandescent, so it blends with existing soft white lamps rather than looking blue next to them. The frosted glass diffuses the LED chips so you don't get hot spots through a thin lampshade, and CRI is 80+, meaning color rendering is in the normal range for residential and hospitality guest rooms.
4) Is the Satco S8542 3-way LED rated for 120V line voltage with no separate driver?
Yes. It runs on 120 volt line voltage straight out of the medium base socket, with the driver built into the bulb. No external transformer or driver to buy. It is not for use on low voltage or 277V circuits.
