SATCO Lighting S16433 12W T8 LED, CCT Selectable, 120-277V, Single or Double Ended, Type B Ballast Bypass

Yes. The S16433 is a Type B ballast bypass lamp, so the existing fluorescent ballast has to be disconnected and line voltage wired directly to the sockets. It runs on 120V to 277V at 50/60Hz, so it works on both residential and commercial circuits once the fixture is rewired. If you want a lamp that drops into a working ballast with no rewiring, you need a Type A plug-and-play lamp instead.

Either way. The 12W T8 LED from Satco is single or double ended, so you can bring line and neutral to one end of the lamp or split them to opposite ends, whichever matches how the fixture is already wired after the ballast comes out.

No, it will not. The S16433 uses a Recessed Double Contact HO/VHO base, the single-pin recessed contact used on high-output and very-high-output fluorescent lamps. Standard T8 fixtures use medium bi-pin sockets, and this lamp will not seat in them. Order this one only if the fixture you are relamping already has RDC HO/VHO sockets.

The lamp is field selectable between 4000K, 5000K and 6500K, so one part number covers cool white through daylight across a building. Output shifts slightly with the setting: 1650 lumens at 4000K, 1750 at 5000K and 1600 at 6500K, with 83 CRI at all three. Useful for property managers standardizing stock instead of holding three SKUs.

No. The 12W T8 LED is non-dimmable and is not a three-way lamp. Wire it to a straight on/off switch; leaving it on an existing dimmer circuit will cause flicker or premature failure.

It is an indoor lamp with a damp location rating, so covered areas where condensation occurs are acceptable, but direct exposure to rain or wet location fixtures is not. Burning position is universal, so it can be mounted horizontally, vertically or in a canopy with no derating.

No. The S16433 is not DLC listed, so it will not qualify for utility programs that require a DLC Qualified Products List entry. It is FCC compliant and Title 24 compliant, which matters for California projects.

Draw is 0.100A at the low end of the voltage range down to 0.043A at the high end, on 12 watts. At 277V that is roughly 43 mA per lamp, so a long run of fixtures loads a branch circuit far less than the fluorescent lamps and ballasts being replaced. Size the circuit from the actual lamp count and your local code.

Output is 360 degrees through a frosted plastic lens, so it throws light all around the tube the way a fluorescent lamp does rather than in a one-sided beam. That matters in open strip fixtures and uplight coves where a directional LED tube would leave the ceiling dark. The base is polycarbonate.
