SATCO Lighting S39679 90W LED HID Replacement, 5000K, Mogul Extended Base, Adjustable Beam Angle, Type B Ballast Bypass, 100-277V

No. The S39679 is a Type B ballast bypass lamp, which means the ballast has to come out and line voltage is wired directly to the socket. Wire it for 100-277V. If you want a lamp that drops into the fixture and runs on the existing ballast untouched, you need a Type A plug-and-play lamp instead, not this one.

The S39679 puts out 12,600 lumens at 90 watts, which is the output range facilities typically use to retrofit 250W to 400W metal halide, depending on how degraded the old lamp was. Judge the swap on lumens rather than wattage, since a 400W MH lamp that has been in service for years is delivering far less than its rated output.

Yes. The 100-277V input range covers 120V, 208V, 240V, and 277V branch circuits, so one part number standardizes a mixed-voltage portfolio. That is the main reason procurement teams specify it across multiple buildings instead of stocking voltage-specific lamps.

It is non-dimmable. Wiring it to a dimmer or a 0-10V control will not work and can shorten lamp life. On/off switching or an occupancy sensor that only switches the circuit is fine.

The S39679 has an adjustable beam angle, so you can set the spread of the light boards to suit the fixture after installation. That matters when you are retrofitting a mix of fixture types on one property, high bays wanting a tighter throw and wall packs or area lights wanting a wider wash, without buying two different lamps.

5000K reads as a crisp white and is the closest common LED color temperature to standard metal halide, so it blends reasonably well in a lot where some fixtures are still HID. CRI is 80+, which is adequate for parking, warehouse, and exterior area lighting. If the rest of your site is already converted to 4000K LED, the 5000K lamp will look visibly cooler alongside it.

Built-in surge protection rated 4KV is included on the S39679, which is worth having on parking lot poles and exterior wall packs where line transients are common. On sites with repeated surge failures, facilities often still add fixture- or panel-level protection on top of it.

The lamp weighs 3.48 lb, which is substantial for a screw-in retrofit. In horizontal-burn or pendant sockets, confirm the porcelain socket and its mounting are sound before hanging that weight off it, since old HID sockets are often brittle. Housing is aluminum, steel, and PBT thermoplastic, with the aluminum doing the heat sinking.

Beyond the lamp itself, plan on wire nuts and a bypass label for each fixture, and replacement mogul sockets where the existing porcelain is cracked or the leads are heat-damaged. The old ballast and capacitor come out and get disposed of. The lamp accepts 100-277V, so no voltage-specific version has to be specified, but each fixture does need to be opened and rewired by a licensed electrician.
