SATCO Lighting S39751 40W LED HID Replacement, 5000K, Mogul extended Base, Adjustable Beam Angle, Type B Ballast Bypass, 100-277V

Yes. The S39751 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 accepts 100 to 277 volts at 50/60Hz, so it works on either a 120V or 277V circuit once the ballast is out of the path. Leaving the old ballast in line will damage the lamp.

The S39751 puts out 5600 lumens at 40 watts with a 5000K daylight color and 80 CRI. Satco rates it as a 300 watt incandescent equivalent. In HID retrofits that lumen package is the range property managers typically use to take out lower wattage metal halide or high pressure sodium parking lot, wall pack, and canopy lamps, and the 5000K output reads distinctly whiter than the yellow of the HPS it replaces, so plan on relamping a whole row at once if you care about matching appearance.

Yes, it is an enclosed rated lamp, so it can go in a sealed or gasketed fixture without voiding the rating. Location rating is damp, and it is listed for indoor or outdoor use. Damp rated means covered outdoor locations such as a canopy, soffit, parking garage, or a gasketed wall pack, not a fixture that takes direct rain or standing water.

No. The S39751 is not dimmable and it is not a three way lamp. Wire it to a straight switched or photocell controlled circuit. If your retrofit spec calls for step dimming or 0-10V control, this lamp will not do it and you need a driver based LED fixture or a dimmable lamp instead.

No. The S39751 is not DLC approved, so it will not qualify for utility rebate programs that require a DesignLights Consortium listing. It is Title 24 compliant and FCC compliant. If the rebate paperwork on your project depends on a DLC listing, specify a DLC listed lamp or fixture instead.

Burning position is base up or base down, so it can be mounted either way. That covers high bay and canopy fixtures where the socket points down as well as post top and bollard fixtures where the socket points up.

Draw is 0.400 to 0.144 amps across the 100 to 277 volt range, high end at low line voltage and low end at 277V. At 277V you are around 0.144A per lamp, so a long run of parking lot or warehouse fixtures loads a branch circuit very lightly compared with the metal halide gear it replaces. Rated life is 50,000 hours.

No, it is fixed at 5000K. CCT selectable is not offered on the S39751, so every lamp out of the box is daylight white. If you are relamping a building where some fixtures are already 4000K, the difference will be visible across the site.

The base and body use aluminum, steel, and PBT thermoplastic, with a white housing and a clear PBT lens over the LEDs. Behind a clear glass refractor or an open acorn globe the white body and clear lens will be visible, which is worth knowing on decorative post tops where the old HID lamp was hidden inside a reflector.
