Satco Lighting S8539 – Frequently Asked Questions

1) Does the Satco S8539 LED PL lamp need the existing ballast, or does it wire direct?
The S8539 is a Type B ballast bypass lamp, so the fixture's existing ballast has to be removed and line voltage wired straight to the sockets. It will not run off an existing CFL ballast. Plan the retrofit as a wiring change, not a drop-in relamp.
2) Will a G24d 2-pin LED PL lamp fit my existing CFL socket?
The S8539 uses a G24d 2-pin base, which matches the 2-pin CFL sockets found on 13W, 18W and 26W quad and twin tube compacts. If your fixture has a 4-pin G24q socket, this lamp will not seat, and it is also a vertical burn design, so the socket needs to be oriented for vertical lamp position.
3) Can I mount the Satco S8539 PL LED horizontally in a fixture?
No. It is specified for vertical lamp orientation, so it belongs in downlights and other fixtures where the socket points the lamp up or down. For a horizontal socket, such as a wall sconce or a horizontal-burn can, you need a PL LED rated for horizontal position instead.
4) How much light does the 9W Satco PL LED put out compared to the CFL it replaces?
1000 lumens from 9 watts. That output sits in the range of a typical 18W to 26W 2-pin compact fluorescent, so you get comparable light at roughly a third to a half of the draw. Beam spread is 120 degrees, which suits downlights, sconces and wall packs rather than any tight-beam application.
5) What color does the Satco S8539 5000K bulb throw?
5000K, a crisp daylight white with no warm cast. That is the usual choice for parking garages, stairwells, back-of-house and shop areas where you want things to read bright and neutral. If the rest of the building is on 3000K or 3500K lamps, this one will look visibly bluer beside them.
6) How long does the Satco 9W LED PL lamp last before relamping?
50,000 average rated hours. On a garage or corridor running 24/7 that is close to six years of continuous burn, which is why maintenance crews move these openings to ballast bypass LED, the ballast comes out of the failure list at the same time.
7) What finish is the Satco S8539 LED PL lamp?
Frost. The diffused lens softens the LED sources so you do not get hot spots or visible diodes through an open downlight trim or a clear fixture lens.
