SATCO Lighting S23152 36/27/18 Wattage Selectable, LED HID Replacement, CCT Selectable, Type B, Ballast Bypass, Extended Mogul Base, 100-277V

Yes. The S23152 is a Type B ballast bypass lamp, so it wires direct to line voltage. The existing metal halide or HPS ballast has to be removed or bypassed and the socket wired straight to 100-277V. Leaving the ballast in circuit will damage the lamp. If you want a lamp that runs on the ballast as-is, you need a Type A plug-and-play retrofit instead, not this one.

Both are selectable on the lamp itself before you install it. Wattage steps 36W, 27W, or 18W, delivering 5040, 3780, or 2520 lumens respectively. Color selects 3000K, 4000K, or 5000K. One SKU covers nine combinations, which is why property managers use it to standardize a parking lot or garage and then dial each fixture to suit. Set it before the lamp goes in the socket, because you will not reach the selectors once it is in a closed housing.

Yes. The enclosure rating covers both open and enclosed fixtures, and it can burn in any position, so base up, base down, or horizontal all work. Location rating is damp, which covers outdoor fixtures with a housing over the lamp, like wallpacks, post tops, and canopies. It is not rated for wet locations where the lamp is directly exposed to rain.

At its top setting the S23152 puts out 5040 lumens at 36W, which is the range commonly used to retrofit lower-wattage metal halide and HPS lamps in wallpacks, garage fixtures, and post tops. Satco lists it at 125W incandescent equivalent. Judge the swap on lumens against the existing lamp rather than on nameplate wattage, since the LED throws 360 degrees and older HID optics waste a lot of light in the reflector.

Yes. It runs 100 to 277 volts at 50-60Hz, so the same lamp goes into 120V house circuits and 277V commercial lighting circuits without ordering a different part. Draw runs 0.360 to 0.130A at 36W, 0.270 to 0.097A at 27W, and 0.180 to 0.065A at 18W, the higher figure at the low end of the voltage range. Useful numbers when you are sizing how many lamps you can hang off one existing branch circuit.

The S23152 is 80 CRI, which is the standard for exterior, garage, warehouse, and general MRO work and well above the HID lamps it replaces. Where it is not enough is retail display, color matching, or anywhere people judge color for a living. Rated life is 50,000 hours, so in a 12-hour-a-night dusk-to-dawn application you are looking at roughly a decade before relamping.

It is a corncob-shape LED lamp with a dark gray housing and a plastic lens over the diodes. The gray body is visible in open fixtures and behind clear glass, which matters on decorative post tops or acorns where the old HID arc tube was less conspicuous. In a closed wallpack or prismatic refractor nobody sees it.
