SATCO Lighting S11950 7W, 18in, T8 Linear LED, Medium Bi-Pin G13Base, 3000K, 700 Lumens, Type B Ballast Bypass

No. The S11950 is a Type B ballast bypass lamp, so the fluorescent ballast has to be removed and line voltage wired directly to the sockets. If you want a lamp that runs on the existing ballast, you need a Type A plug-and-play tube instead. The S11950 accepts 120V to 277V line voltage at 50/60Hz, so it covers both residential and commercial circuits once the fixture is rewired.

Yes. It is an 18-inch T8 lamp with a medium bi-pin (G13) base, which is the same lamp length and socket as a standard 15W F15T8 fluorescent tube. Burning position is universal, so it can be mounted horizontally, vertically, or at any angle.

No. The S11950 is non-dimmable and has no three-way function. Wire it to a straight on/off switch. If a dimmed circuit is already in place, either change the control or pick a lamp rated dimmable.

No. The S11950 is not DLC approved, so it will not qualify for utility rebate programs that require a DLC listing. It is Title 24 compliant and FCC compliant. If a rebate is driving the project, specify a DLC listed lamp.

The S11950 puts out 700 lumens at 7 watts, which Satco rates as a 75W incandescent equivalent. CRI is 83 and the beam spread is 160 degrees, so light spreads broadly across the fixture rather than throwing a narrow pattern. For a short utility, cove, or under-cabinet strip that is a direct light-output swap for a typical 18-inch fluorescent.

It is an enclosed rated lamp, so it can go in a closed or lensed fixture without the heat trapping shortening its life. Location rating is damp and it is listed for indoor use, which covers bathrooms, kitchens, and covered areas, but not direct wet exposure outdoors.

3000K is warm white, closer to the tone of an incandescent or halogen than the cool 4000K and 5000K tubes common in offices and shops. The S11950 is a fixed 3000K lamp, not CCT selectable, so it will not blend with 4000K or 5000K fixtures in the same space. For a fleet standardization, order all lamps in one color temperature.

Each S11950 draws 0.058 to 0.025 amps depending on applied voltage across the 120V to 277V range, with the lower draw at the higher voltage. At 7 watts per lamp, the load per tube is small, so circuit capacity is rarely the limit on a retrofit of this lamp. Size the circuit to the total connected load of the fixtures you are feeding.

Average rated life is 50,000 hours. On a 12-hour-a-day schedule that is more than 11 years of operation, which is why MRO and property maintenance buyers standardize on this type for fixtures that are awkward to reach.

The lens is glass with a frost finish, which diffuses the LEDs so you do not see hot spots through an open fixture. The housing is white and overall construction is glass and plastic. Lamp weight is 0.19 lb.
