SATCO Lighting S39916 14W T8 LED, 4Ft, 5000K, Medium Bi Pin Base, 50000 Avg Rated Hours, 1800 Lumens, Type B, Ballast Bypass

No. The S39916 is a Type B ballast bypass lamp, so the existing fluorescent ballast has to come out and line voltage has to be wired direct to the sockets. It accepts either single-ended or double-ended wiring, which gives the electrician flexibility on how the tombstones are fed. If you want a lamp that runs on the ballast already in the fixture, you need a Type A plug-and-play tube instead.

Only if those are 5000K daylight lamps. The S39916 is fixed at 5000K, a cool daylight white, and it is not a CCT selectable lamp, so there is no field switch to drop it to 3500K or 4000K. Mixing it in a space with 4000K tubes will read as an obvious color difference. Color rendering is 82 CRI.

It runs on any line voltage from 120V through 277V at 50/60Hz, so the same lamp works on residential 120V circuits and on 277V commercial lighting branch circuits. Current draw is 0.117A down to 0.051A depending on where in that range you land.

For general ambient lighting in corridors, storage, parking structures and back-of-house, yes. The lamp puts out 1800 lumens at 14 watts, which Satco rates as a 75W incandescent equivalent, with a 210 degree beam spread so the light washes out of the fixture rather than throwing a narrow pattern. If you are lighting a space that currently runs high-output tubes for task work, count your fixtures and lamps per fixture against the lumen total before committing a whole floor.

It carries a damp location rating and is listed for indoor or outdoor use, so covered exterior areas, parking decks and similar damp spots are within rating. Damp is not wet: it should not be used where it will be exposed to direct water or driving rain unless the fixture itself provides that protection.

Yes. Burning position is universal, so it can run horizontally in a troffer or strip, vertically in a cove or wall-mount, or at any angle without affecting rated life. Rated average life is 50,000 hours.

Glass. Both the lens and base material are glass with a gloss white finish and a white housing. Worth knowing for handling and for spaces where a shatter-resistant coated or plastic-bodied tube is required, such as food prep or healthcare areas under a glass-exclusion policy.

No. The S39916 is not a three-way lamp. It is a ballast bypass tube wired to line voltage, so plan on switched on/off control rather than dimming for this lamp.

The lamp is FCC compliant, so its driver meets the federal limits on conducted and radiated emissions. That is the spec to point to if you are installing near AV, radio, or medical monitoring equipment and someone asks.
