SATCO Lighting S21413 14W LED PL, CCT Selectable, Lumens Selectable, Type B, Ballast Bypass, White Finish, 120/277V

No. The S21413 is a Type B, ballast bypass lamp, which means it runs on line voltage directly and the existing CFL ballast has to be removed or bypassed in the fixture before the lamp goes in. Drop it into a socket still fed by a ballast and it will not operate correctly. If you want a lamp that plugs straight into a working ballast with no rewiring, you need a Type A plug-and-play PL lamp instead.

Yes. The Satco S21413 is rated 120/277 volt, so the same lamp works on standard 120V residential and light commercial circuits and on the 277V circuits common in commercial and institutional buildings. For a property manager or MRO buyer standardizing across a portfolio, that means one part number covers both circuit types instead of stocking two.

Both are selectable on the lamp itself. The S21413 is CCT selectable and lumens selectable, so one lamp covers several color temperatures and several light output levels, and you pick the setting at install. That is useful when you are matching color to fixtures already in a corridor or lobby, or tuning output down in a space where the original CFL was too bright, without ordering a different SKU for each combination.

The install is a rewire, not a lamp swap. With a Type B lamp like the Satco S21413, line voltage has to be brought directly to the socket, which means removing the ballast or cutting it out of the circuit and rewiring the lampholder. That is licensed electrician work in most commercial settings, and it is done once per fixture, after which future relamping is a straight swap. Budget the labor per fixture when you are quoting a retrofit across a building.

It is a 14 watt LED PL lamp intended to take the place of a plug-in compact fluorescent PL, with the ballast bypassed. The 14 watts is the LED draw, not the CFL wattage it substitutes for, and because output is lumens selectable you set the brightness to match what the space needs rather than matching the old lamp's wattage number.
