SATCO Lighting S39926 12W T8 LED, 3ft, 3000K, Medium Bi Pin Base, 50000 Avg Rated Hours, 1400 Lumens, Type B, Ballast Bypass

No. The S39926 is a Type B ballast bypass lamp, which means the fluorescent ballast has to be removed and line voltage wired direct to the sockets. It accepts either single-ended or double-ended wiring, so it works with either rewire method. If you want a lamp that runs on the existing ballast with no rewire, you need a Type A plug-and-play tube instead.

It is rated 120V to 277V at 50/60Hz, so the same lamp covers 120V residential circuits and 277V commercial lighting branch circuits. Current draw runs 0.100 to 0.0433A across that voltage range.

Only if your existing tubes are also 3000K. The S39926 is a fixed 3000K warm white with a CRI of 82, and it is not CCT selectable, so there is no switch to dial it to 3500K or 4000K. Most commercial offices and warehouses were relamped at 4000K or 5000K, so check what is in the fixture before mixing, otherwise you will see the color shift down the run.

1400 lumens from 12 watts, with Satco rating it as a 50W incandescent equivalent. Rated life is 50,000 hours, so in a space running 12 hours a day you are looking at years between relamps, which is the main reason facilities teams standardize on these for corridors and back-of-house.

It carries a damp location rating and Satco lists it for indoor and outdoor use, which covers covered walkways, canopies, and garage fixtures where the lamp is shielded from direct rain. It is not a wet location lamp, so anything with direct water exposure needs a different rating.

No. The S39926 is not a three-way lamp, and as a ballast bypass tube it is wired straight to line voltage. Put it on a standard switched circuit. If you need dimming in the space, specify a dimmable driver-based fixture rather than this lamp.

Yes, the burning position is universal, so it can be run horizontal, vertical, or at any angle without affecting rated life. The 210 degree beam spread means the light is thrown well past a flat 180, so rotating the tube in the socket to aim the output is not critical.

Glass, with a gloss white lens finish that diffuses the LEDs so you do not see individual diodes through the cover. Handle and pack it like a fluorescent tube rather than a shatter-resistant plastic sleeve.
