SATCO Lighting S39798 40W LED HID Replacement, 2700K, Mogul extended Base, Adjustable Beam Angle, Type B Ballast Bypass, 100-277V

Yes. The S39798 is a Type B ballast bypass lamp, so the existing HID ballast has to be removed or bypassed and line voltage wired directly to the socket. It runs on 100-277V, 50/60Hz, drawing 0.400-0.144A depending on supply voltage. Leaving a magnetic or electronic HID ballast in the circuit will damage the lamp.

Yes on the enclosure, with a limit on the location. The lamp is enclosed rated, so it can be installed in a closed fixture without voiding its thermal design, and it is listed for indoor or outdoor use. But the location rating is Damp, not Wet, so it belongs in a fixture that keeps direct water off the lamp, such as a gasketed wall pack or a covered soffit, rather than an open exposure to rain.

No. At 2700K this lamp is a warm, soft white closer to incandescent or high pressure sodium in appearance, while metal halide typically reads as a cool white in the 4000K range. Color temperature is fixed at 2700K, not selectable, so if you are matching existing MH openings across a site you want a cooler lamp instead. CRI is 80, so color rendering is adequate for general area and common-area lighting.

Output is 5120 lumens at 40 watts, which Satco rates as a 300W incandescent equivalent. In practice that output band is where you swap out a low-wattage metal halide or high pressure sodium lamp of roughly 100W. Compare your existing lamp's lumen output rather than its wattage, since HID lamps lose a large share of their output over life while this lamp is rated 50,000 hours.

It is not dimmable and is not a three-way lamp, so leave it off dimmer circuits entirely. Simple on/off switching is fine, which includes photocell or occupancy control that just cuts line power, since the lamp is wired directly to 100-277V with no ballast in the circuit.

Not through DLC. The lamp is not DLC listed, which is the qualification most commercial utility programs key their LED rebates to. It is Title 24 compliant and FCC compliant, so it can be specified on California energy-code work even though it will not carry a DLC-based incentive.

The lamp weighs 1.85 lb, which is normal for an LED HID retrofit but well above the HID lamp it replaces. Housing is aluminum, steel and PBT thermoplastic with a clear PBT lens. In an older porcelain socket, especially a pendant mogul socket on a flexible lead, check that the socket and its mounting can carry that weight without sagging, and support the lamp if the fixture is mounted base down at an angle.
