SATCO Lighting S8757 8W LED PL Medium Base, 3500K, Type B, Ballast Bypass, 960 Lumens, 50000 Avg Rated Hours, 120 degree Beam Angle

Yes. The S8757 is a Type B ballast bypass lamp, so it runs on line voltage and the fixture's existing CFL ballast has to be removed and the sockets rewired to line voltage before installation. Leaving the ballast in place will damage the lamp. It accepts 120V to 277V at 50/60Hz, so it works on either common commercial circuit.

No. The 8W S8757 is non-dimmable and not three-way capable. On a dimmer it will flicker, buzz, or fail early. For dimming-controlled spaces, pick a lamp that lists dimming support; for this one, use a standard on/off switch or occupancy sensor rated for non-dimming LED loads.

Yes, it is an enclosed rated lamp, so it can go in sealed or closed-top fixtures where heat builds up. Burning position is universal, so base-up, base-down, or horizontal all work.

It draws 8 watts and puts out 960 lumens, which Satco rates as a 40W incandescent equivalent. Color is 3500K neutral white with a CRI of 83, and the beam spread is 120 degrees, so it throws wide rather than spotting. Frosted lens keeps the diodes from showing as hot spots.

The S8757 is fixed at 3500K and is not CCT selectable, so what you order is what you get. 3500K reads neutral white, between the warmer 3000K used in hospitality and the cooler 4000K common in offices and back-of-house. If your other fixtures are 4000K, this lamp will look noticeably warmer beside them, so standardize a whole area at once rather than swapping one lamp at a time.

No on both counts. It is not DLC listed, so it will not qualify for utility rebate programs that require DLC, and it is not BAA compliant, which rules it out on Buy American Act federal projects. It is FCC compliant. For rebate-driven retrofits, specify a DLC-listed lamp instead.

No. Satco flags this lamp as non-compliant for California, so it should not be specified for jobs in that state. Choose a California-compliant LED PL lamp for those projects.

Current runs 0.067A at the low end of the voltage range down to 0.029A at 277V, at 50/60Hz. That is a small enough draw that a corridor or stairwell circuit can carry a lot of them, but do your count on the actual supply voltage rather than the 8W figure alone.

Rated at 50,000 average hours. On a stairwell or corridor burning 24/7 that is roughly five and a half years of continuous run time, which is the main argument for pulling the ballast once and going Type B rather than repeating CFL swaps.
