SATCO Lighting S28715 80W LED HID Replacement, 5000K, Mogul extended Base, Type B Ballast Bypass -277-347V

No. The S28715 is a Type B ballast bypass lamp, which means the existing metal halide or HPS ballast has to be removed and line voltage wired directly to the mogul socket. Leaving the ballast in circuit will damage the lamp. Plan on an electrician opening the fixture and rewiring the socket before the lamp goes in.

Both. The 80 watt S28715 is built for a 277-347 volt input range, so it covers 277V commercial circuits and 347V Canadian industrial service. It will not operate on 120V or 208/240V lines, so check the voltage at the fixture before ordering; a different voltage version is needed for standard 120-277V applications.

Output is 10,640 lumens at 80 watts, 5000K daylight white with 80+ CRI. That lumen package puts it in range of the 250 watt metal halide lamps commonly found in parking lot and warehouse fixtures, where mean lumens drop well below initial over life. Compare against the actual maintained lumens of the lamp you are pulling rather than its nameplate wattage.

No. The S28715 is non-dimmable. Wire it to a straight switched or contactor-controlled circuit. If a site needs step dimming or occupancy-based level control, the control has to live in a different product; on-off photocell or timeclock switching is fine.

The lamp weighs 3.5 lb, which is a lot more than the HID lamp coming out. Aging porcelain mogul sockets and thin socket brackets can sag or crack under that load, especially base-up or horizontal. Inspect the socket and its mounting while the fixture is open for the ballast bypass rewire, and replace a tired socket at the same time.

The order number is Satco S28715, clear finish, and that is the single configuration: 80 watts, 5000K, mogul extended base, Type B bypass, 277-347V. If you need 120-277V or a different color temperature, that is a separate Satco number, not an option on S28715.

5000K is the daylight-white point most facilities pick for parking structures, warehouses, and exterior area lighting because it reads as crisp and matches the cool appearance of the metal halide it typically replaces. With 80+ CRI color rendering is adequate for traffic and storage areas. If the openings alongside it are already 4000K, the S28715 will look noticeably cooler next to them.

Body construction is aluminum and plastic, the aluminum handling heat sinking for the LEDs. It is manufactured in China. Those are the facts to quote if a procurement spec asks for material of construction or country of origin on a lamp submittal.
