SATCO Lighting S11766 14W, 4 Foot LED, T8, CCT Selectable, Type B Ballast Bypass, G13 Base, 120-277V

No. The S11766 is a Type B ballast bypass lamp, which means the existing fluorescent ballast has to be removed and line voltage wired directly to the sockets. If you want a lamp that runs on the ballast already in the fixture, you need a Type A plug-and-play tube instead. Budget the labor for a rewire on every fixture you convert.

It is a CCT selectable lamp offering 3000K, 3500K, 4000K, 5000K and 6500K from the one tube. Output shifts slightly with the setting: 1700 lumens at the two warmer settings and 1800 lumens at 4000K and above. For a property manager stocking one SKU across offices, corridors and back-of-house, that is a single lamp covering warm office white through daylight.

Yes. It operates across 120V through 277V at 50/60Hz, so the same lamp works on residential 120V and on 277V commercial lighting branch circuits. Current draw runs 0.117A down to 0.051A across that voltage range, which is what you use when sizing how many tubes you can hang on a circuit.

It uses a G13 medium bi-pin base, the same pin spacing as a standard 4 foot fluorescent T8, so it seats in existing lampholders. With a Type B ballast bypass lamp, wiring convention matters: confirm whether the lamp is single-ended or double-ended before you land conductors on the sockets, since that decides how the fixture is rewired.

The S11766 puts out 1700 to 1800 lumens depending on the color setting, drawing 14 watts, and Satco rates it as a 75W incandescent equivalent. In a typical 2-lamp or 4-lamp troffer that reads as a usable office-level replacement, but if your space is lit to a tight footcandle spec, do the math on fixture count before committing to a full building swap.

It carries a damp location rating, so covered walkways, garages, canopies and bathrooms are fine. Direct rain or hose-down washdown is not, that needs a wet-rated lamp or a sealed wet-location fixture around it.

The lens is frosted glass, which diffuses the diodes rather than showing them as a line of hot spots, and the beam spreads 210 degrees so light wraps around the tube rather than firing straight down. CRI is 80, standard for commercial office, classroom and corridor work. For color-critical retail or medical exam areas you would want a 90+ CRI lamp.

Burning position is universal, so the tube can run horizontally in a troffer, vertically in a wall fixture, or base-up in a strip without affecting rated life. Rated life is 50,000 hours.

It is not a three-way lamp. Plan it as a full-output tube on a standard switched or occupancy-sensor controlled circuit.

The lamp uses a glass lens with glass and plastic base construction. Glass-bodied LED tubes are not shatter-coated unless stated, so for food prep areas, gyms or anywhere a code requires shatter protection, specify a coated or plastic-bodied tube or a lensed fixture instead.
