SATCO Lighting S16443 48W T8 LED, CCT Selectable, 120-277V, Single or Double Ended, Type B Ballast Bypass

No. The S16443 is a Type B ballast bypass lamp, so the existing fluorescent ballast has to be removed or disconnected 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 rewiring each fixture before you commit to a quantity.

Both. The 48W Satco T8 LED accepts single ended or double ended wiring, which lets it work with whichever socket wiring you end up with after the ballast is removed. It runs on 120V through 277V at 50/60Hz, so the same lamp covers 120V residential-style circuits and 277V commercial lighting branch circuits.

The lamp is field selectable between 4000K, 5000K and 6500K, so one part number covers cool white through daylight. Output shifts slightly with the setting: 6700 lumens at 4000K, 6900 at 5000K and 6600 at 6500K. CRI is 83 at all settings. For facilities standardizing a building, you can stock one lamp and match whatever is already installed in each area.

No. The S16443 is not DLC approved, so it will not qualify for the utility rebate programs that require a DLC listing. It is Title 24 compliant and FCC compliant. If a rebate is part of how you are funding a retrofit, confirm the program's list and pick a DLC-listed lamp instead.

No. The 48W Satco T8 LED is non-dimmable and is not three-way capable. On a dimming circuit it can flicker or fail, so wire it to a straight switched line. If the space needs dimming control, specify a dimmable linear LED lamp or a dedicated LED strip fixture with a compatible driver.

It carries a damp location rating and is listed for indoor use, so it suits covered areas that see humidity, like warehouses, stairwells and covered walkways, provided the lamp is not exposed to direct water. It is not a wet location lamp. Burning position is universal, so it can be mounted horizontally, vertically or in any orientation the fixture allows.

Draw runs 0.400A at the low end of the voltage range down to 0.173A at the high end, at 48 watts per lamp. Use the current figure for your actual branch voltage when you load-count a circuit: lamps on 277V pull far less current than the same lamps on 120V, so a 277V run carries many more fixtures before you hit the breaker limit.

The lamp is a 360 degree beam spread with a frosted plastic lens, so it throws light all the way around the tube rather than in one direction. That works in open strip and industrial fixtures where you want light bouncing off a white reflector or ceiling. In a fixture with a solid reflector behind the lamp, some of that output is wasted, so a directional tube is the better choice there.

Average rated life is 50,000 hours. The base is polycarbonate rather than glass-and-metal, which matters in areas where lamps get knocked during handling. Satco rates the output as equivalent to a 150W incandescent, with 6700 to 6900 lumens depending on the color setting.
