SATCO Lighting S13120 70W LED HID Replacement, 2700K, Mogul extended Base, Type B Ballast Bypass, 100-277V

No. The S13120 is a Type B ballast bypass lamp, which means it runs on line voltage directly. The existing HID ballast and igniter have to be removed or bypassed and the socket wired straight to 100-277V line power before the lamp goes in. Drop it into a live ballasted fixture and you will damage it.

At 10,500 lumens, the S13120 lands in the range typically covered by a 250W to 320W metal halide or high pressure sodium lamp, while drawing 70 watts. For a property manager relamping a parking garage or warehouse bay, that is the comparison that matters: same light on the floor, far less load per fixture.

It accepts 100-277V, so the same lamp covers 120V, 208V, 240V and 277V circuits. For an MRO buyer standardizing across a campus with mixed voltages, that means one part number on the shelf instead of voltage-specific stock.

2700K is a warm, incandescent-like white. It reads comfortable and residential, which suits hospitality exteriors, lobbies, courtyards and decorative post tops. For warehouse, garage and industrial bays most spec writers go 4000K or 5000K instead, because the cooler color renders surfaces and signage better. The S13120 is the 2700K version, so pick it when the look matters more than crispness.

Yes, the lamp is dimmable, and it carries a CRI of 80+. That combination makes it workable in hospitality and common-area spaces where levels get trimmed at night. Dimming depends on the control being on the line-voltage side, since this is a ballast bypass lamp wired direct.

The S13120 has built-in surge protection rated 4KV. On outdoor pole and wall-pack circuits, where switching transients and nearby lightning activity take out cheaper retrofits, that built-in protection is the spec to point at. It does not replace a dedicated fixture-level SPD on a known problem circuit.

Order by Satco part number S13120. It is the 70W, 2700K, mogul extended base, Type B ballast bypass version in clear. Satco builds this family across multiple color temperatures and base styles, so the number is what separates the 2700K bypass lamp from the cooler and ballast-compatible variants.

The lamp weighs 2.43 lb. That is heavier than the HID lamp coming out, so in horizontal or pendant sockets check the socket and its mounting are sound before hanging it, particularly in older fixtures with brittle porcelain or a tired socket shell.

Construction is aluminum with a polycarbonate lens. The aluminum body is the heat sink, which is why these lamps want airflow; verify the fixture is rated for enclosed use with this lamp before you seal it into a tight glass refractor. Polycarbonate optics hold up better than glass to impact on exterior poles and garage fixtures.
