SATCO Lighting S28727 6W LED PL 2-PIN, 3500K, 600 Lumens, GX23 Base, 50000 Avg Rated Hours, 360 degree Beam Angle, Type B, Ballast Bypass

No. The S28727 is a Type B ballast bypass lamp, so it runs on line voltage direct to the socket. The existing CFL ballast has to be removed or bypassed and the sockets rewired to line voltage before the lamp goes in. Drop it into a socket still fed by a ballast and it won't run correctly. It accepts 120-277 volt, so it works on either a 120V or 277V circuit once wired direct.

Just wire and the labor. Nothing beyond the lamp itself ships with it, and the retrofit is on the fixture side: pull or bypass the ballast, land line and neutral on the GX23 socket, then install. Existing GX23 sockets in good condition can usually be reused; brittle or heat-damaged ones get replaced at the same time. This is licensed electrical work in most commercial settings.

At 600 lumens the S28727 covers the light output of the 7W to 9W twin-tube PL compact fluorescents commonly found in stairwells, corridors and wall sconces, while drawing 6 watts. The 360 degree beam angle means it throws light all the way around the tube rather than in one direction, so it behaves like the CFL it replaces in an open or diffused fixture.

3500K is neutral white, between the warmer 3000K look and the cooler 4000K used in a lot of commercial spaces. If the other fixtures on the floor are 3000K or 4000K, the S28727 will read visibly different next to them. For a fleet of openings or a whole corridor, standardize on one temperature rather than mixing.

Rated at 50,000 average hours. In a stairwell or corridor running roughly 24/7 that's about 5.7 years of continuous burn, against the 10,000 to 20,000 hours typical of the twin-tube CFLs these go into. That is the argument for the retrofit on a large property: the labor of rewiring the socket once buys years without a relamp truck roll.

The S28727 is not a dimming lamp. It runs line voltage direct at 120-277 volt through a bypassed socket, so put it on a straight switched circuit. A standard occupancy sensor that simply switches the line on and off is fine; a dimming control or a sensor with a dimming output is not.

Frost. The diffused finish softens the LED sources inside the tube, which matters in an open fixture or an exit-adjacent sconce where the lamp is visible rather than behind a lens.

S28727 is the Satco Lighting number for the 6 watt, 3500K, 600 lumen GX23 2-pin ballast bypass lamp. Satco runs this lamp in several color temperatures under adjacent numbers, so order by the full number rather than by wattage and base alone if you need 3500K specifically.
