SATCO Lighting S11765 12W, 3 Foot LED, T8, CCT Selectable, Type B Ballast Bypass, G13 Base, 120-277V

No. The S11765 is a Type B ballast bypass lamp, so the fluorescent ballast has to be removed and line voltage wired directly to the sockets. Dropping it into a fixture that still has a working ballast will not work. If you want a lamp that runs on the existing ballast, you need a Type A (plug-and-play) tube instead.

Five selectable CCTs: 3000K, 3500K, 4000K, 5000K and 6500K, chosen on the lamp itself. That lets a property manager stock one tube and match 3500K offices and 5000K back-of-house from the same box. Output follows the setting: 1350 lumens at 3000K and 3500K, 1450 lumens at 4000K, 5000K and 6500K.

Yes, it is rated 120V through 277V at 50/60Hz, so the same lamp runs on residential 120V branch circuits and on 277V commercial lighting panels. Current draw is 0.100A at the low end of the voltage range down to 0.043A at the high end, which matters when you are counting lamps on a circuit.

It is DLC approved, which is what most utility prescriptive rebate programs require for linear LED replacement lamps, and Satco lists it as Title 24 compliant for California work. It is also FCC compliant. Those three are the boxes an institutional or government procurement spec usually asks about on a tube retrofit.

The S11765 draws 12 watts and puts out 1350 to 1450 lumens depending on the CCT setting, with an 80 CRI and a 210 degree beam spread so light is thrown broadly rather than pinched into the fixture. Satco rates it as a 50W incandescent equivalent. For a lamp-for-lamp retrofit in a 3-foot strip or troffer it is a direct physical swap once the ballast is bypassed.

Damp location rated, so covered walkways, garages and similar damp spaces are acceptable. It is not rated for wet locations, meaning direct water contact or exposure to rain requires a different lamp or a sealed wet-location fixture.

Burning position is universal, so it can be installed horizontally, vertically, or at any angle without affecting operation. That makes it usable in wraps, strips, troffers and vertical stairwell fixtures from the same part number.

The lamp uses a frosted glass lens with a glass and plastic base construction and a white housing. Glass means you should treat it like a conventional fluorescent tube for handling and breakage. If your facility requires shatter-resistant lamps, specify a coated or plastic-bodied tube instead.

Rated average life is 50,000 hours. On a 12-hour-a-day schedule that is roughly 11 years of service, which is the argument for a ballast bypass conversion: you remove the ballast as a failure point at the same time you remove the lamp maintenance cycle.

It is not a three-way lamp, and it is a ballast bypass tube wired direct to line voltage. For dimmed zones, specify a tube and driver system listed for dimming rather than this one.
