SATCO Lighting S13121 70W LED HID Replacement, 4000K, Mogul extended Base, Type B Ballast Bypass, 100-277V

Yes. The S13121 is a Type B ballast bypass lamp, so line voltage has to be wired straight to the socket and the existing HID ballast removed or disconnected. It will not run through a metal halide or HPS ballast. Input is 100-277V at 50/60Hz, drawing 0.700-0.253A across that range, so it covers both 120V and 277V fixtures once the ballast is out of the circuit.

At 70 watts the lamp puts out 10,500 lumens, which is in the range of a 250W metal halide or HPS lamp on the HID side, and it is rated as a 250W incandescent equivalent. The 360 degree beam spread means it throws light all around the lamp body the way an HID corncob does, rather than in one direction, so it suits open reflectors, high bays, and post tops rather than tight-optic fixtures.

Yes, it's an enclosed rated lamp, so sealed fixtures are allowed, and it carries a damp location rating. Damp covers covered and sheltered outdoor spots like parking garages, canopies, and soffits. It is not wet rated, so don't use it where it will take direct rain or standing water.

The S13121 is fixed at 4000K neutral white with 80+ CRI. It is not CCT selectable, so if you want 3000K or 5000K you need a different Satco part number. 4000K reads close to the white light crews expect in garages, warehouses, and loading areas, and it is the usual choice when you're standardizing a mixed site on one color.

Dimming is supported on this lamp. Three-way operation is not, so it won't step through levels in a three-way socket. Because it's a ballast bypass lamp, any dimming has to be done on the line voltage side of the socket, not through old HID gear.

The S13121 is listed as Title 24 compliant and FCC compliant. It is not DLC approved, which matters if your utility rebate program requires a DLC-listed product; for those jobs you'd need to spec a DLC qualified lamp instead.

Rated life is 50,000 hours, which is why these go into garages, high bays, and pole heads where relamping means a lift. The lamp weighs 2.43 lb, built with an aluminum and polycarbonate body in white with a clear polycarbonate lens, so confirm the socket and any lamp support in an older HID fixture can carry that weight in a horizontal or base-up position.

A Type B lamp like the S13121 bypasses the ballast entirely: more labor up front because an electrician has to rewire the socket to line voltage, but you lose the ballast as a failure point and the lamp runs on anything from 100 to 277V. A plug-and-play (Type A) lamp drops into the existing socket with the ballast left in place, which is faster for a single relamp but keeps you tied to a ballast that will eventually fail. For fleet retrofits across a portfolio, Type B is the usual call.
