SATCO Lighting S21414 18W LED PL, CCT Selectable, Lumens Selectable, Type B, Ballast Bypass, White Finish, 120/277V

Yes. The S21414 is a Type B ballast bypass lamp, so it runs on line voltage directly. The existing fluorescent ballast has to be removed or bypassed and line voltage wired to the sockets before the lamp goes in. Drop it into a fixture with a live ballast still in the circuit and it will not operate correctly.

It does. The 18 watt LED PL is rated 120/277 volt, so the same lamp covers residential 120V and the 277V circuits common in commercial buildings. For an MRO buyer standardizing across a facility, that means one part number for both voltage systems.

No color decision is made at order time. The S21414 is CCT selectable, meaning the color temperature is chosen on the lamp itself at install, so one stocked lamp can serve a warm office and a cooler back-of-house area. Property managers keeping one SKU on the shelf for mixed spaces get that flexibility without ordering multiple part numbers.

The lamp is lumens selectable as well as CCT selectable, so output is set at the lamp rather than fixed by the part number. That matters where the same fixture type is used in corridors and in work areas and you want different light levels from one stocked item.

Type B suits jobs where the ballast is failing or you want it out of the maintenance picture for good, since the lamp runs on line voltage and there is no ballast left to replace later. The trade-off is an electrician at each fixture to rewire the sockets. A plug-and-play (Type A) lamp installs into an existing working ballast with no rewiring, which is faster for a large retrofit, but it stays dependent on that ballast. The S21414 is the Type B, ballast bypass version.

Satco S21414. It is the 18 watt LED PL with CCT and lumen selection, Type B ballast bypass wiring, white finish, rated 120/277 volt. That is the number to quote for reorders or to match against a distributor line sheet.
