SATCO Lighting S39768 30W LED HID Replacement, 2700K, Medium Base, Adjustable Beam Angle, Type B Ballast Bypass, 100-277V

Yes. The S39768 is a Type B ballast bypass lamp, so it wires direct to line voltage and the existing HID ballast has to be removed or bypassed. Leave the ballast in the circuit and the lamp won't operate correctly. It accepts 100 to 277 volts at 50/60Hz, drawing 0.300 to 0.108A depending on where in that range you land, so it works on both 120V and 277V commercial circuits once rewired.

Yes, it's an enclosed rated lamp, so a sealed or gasketed fixture is acceptable. It also carries a damp location rating and can be used indoors or outdoors, which covers covered walkways, canopies, and parking garage fixtures. Damp is not wet, so keep it out of anything exposed to direct water spray or standing water.

No to both. This lamp is non-dimmable and not three-way, so it needs a straight switched circuit. Putting it on a dimmer or a three-way socket can cause flicker, buzzing, or early failure. If the fixture is on a dimmer, either remove the dimmer from that circuit or choose a lamp rated dimmable.

2700K is warm white, close to the color of an old incandescent or a warm CFL, and it is noticeably yellower than the 4000K or 5000K most HID retrofits land on. It won't match neutral or daylight lamps on adjacent fixtures. For hospitality, lobby, and residential multi-family common areas where a warm look is wanted, this is the right color; for parking and back-of-house standardized at 4000K or higher, pick a cooler version. CRI is 80, and the color is fixed, not selectable.

The LED panels fold to set the beam spread at 120, 150, or 260 degrees. Tighter settings push more light downward, which suits a wall pack or a shoebox where you want the output out the bottom; 260 degrees spreads close to omnidirectional for a post top or open acorn globe. You set it at install, it isn't adjustable from the ground afterward.

Satco rates the S39768 as a 200W incandescent equivalent, putting out 3840 lumens from 30 watts. For MRO retrofits that's the practical swap range for low-wattage HID and high-wattage incandescent or CFL fixtures. Compare the lumen number to the lamp you are pulling rather than the old wattage, since HID output drops substantially over its life.

Burning position is universal, so base up, base down, or horizontal are all acceptable. That matters on retrofits where the old HID lamp had a restricted operating position. In a horizontal or base-up enclosed fixture, heat collects around the base, so make sure the fixture is genuinely the one you want a lamp this warm-white in, since it is fixed at 2700K with no CCT selection.

No. The S39768 is not DLC approved, so it will not qualify for utility programs that require a DLC listing. It is Title 24 compliant and FCC compliant. If the rebate paperwork on your retrofit hinges on DLC, you'll need a different lamp for that project.

Average rated life is 50,000 hours. The body combines aluminum and steel with thermoplastic (PBT) for heat handling, the housing is white, and the lens is clear PBT. Aluminum in the base assembly is what carries heat away in an enclosed fixture, which is the usual failure point on cheap corncobs.

Order Satco S39768. It ships as one configuration, a clear-lensed 30W 2700K medium base Type B corncob, so there are no finish or color options to specify. Quote the S39768 number directly when standardizing a lamp list, since Satco's corncob range runs many close wattage and CCT variants.
