SATCO Lighting S9864 9W LED PL 2-Pin, 4000K, 900 Lumens, G24d Base, 50000 Avg Rated Hours, Type A, Ballast dependent

No, and in fact you can't. The S9864 is a ballast-dependent (Type A) lamp, meaning it runs off the existing CFL ballast in the fixture. Leave the ballast in place and the lamp drops into the socket. If your fixture's ballast has failed or you intend to bypass it, this is the wrong lamp for the job.

No. The S9864 has a G24d 2-pin base, which only seats in a 2-pin G24d socket. Four-pin fixtures use G24q bases and the pin arrangement will not mate. Check the existing lamp: if it has four pins, you need a 4-pin version instead.

No. The S9864 is not dimmable. On a dimming circuit expect flicker, buzz, or no start at all. For dimmed spaces, keep the circuit at full line voltage or choose a fixture-level LED retrofit rated for dimming.

Yes, it's an enclosed-rated lamp, so a closed drum, jar, or lensed downlight is fine. It also carries a damp location rating, which covers covered exterior soffits, breezeways, and bathrooms. It is not rated for wet locations where water can hit the lamp directly.

It draws 9 watts and puts out 900 lumens, which covers the common 13W 2-pin CFL output range in a PL downlight or wall sconce. Satco rates it as a 40W incandescent equivalent. If your existing lamp is an 18W or 26W CFL, expect less light from this one.

Either way. The S9864 is rated for base up or base down burning position, so it works in a recessed can, a surface ceiling fixture, or a horizontal wall sconce without affecting rated life.

4000K is neutral white, cooler and cleaner-looking than the 2700K to 3000K warm white common in residential corridors and hospitality. It's the usual choice for offices, stairwells, garages, and back-of-house. The color temperature is fixed, not field selectable, so if your other openings are 3000K this lamp will read noticeably bluer next to them. CRI is 82.

No. The S9864 is not DLC listed, so it won't qualify for utility programs that require DesignLights Consortium listing. If a rebate is driving the spec, you'll need a DLC-qualified product. The lamp is FCC compliant and lawful for sale in California.

Rated at 50,000 average hours. On a 12-hour-a-day corridor schedule that's over 11 years of service, which is the main reason facilities swap 2-pin CFLs for these rather than restocking CFL tubes. Keep in mind the fixture ballast still has to survive, since the lamp depends on it.

Yes. The beam spread is 120 degrees with a frosted lens, so it throws a broad, diffused wash rather than a spot. That suits general ambient lighting in corridors, restrooms, and lobbies. For accent or task aiming you want a directional lamp instead.

The base and housing are aluminum and plastic with a white housing and a frosted lens. The aluminum section acts as the heat sink, which is why the lamp tolerates enclosed fixtures.
