SATCO Lighting S49392 36W LED HID Replacement, 80 CRI, 5000K, Type B, Ballast Bypass, Medium Base, Economy Hi-Pro

The ballast has to go. The S49392 is a Type B, ballast bypass lamp, which means it runs on line voltage direct to the socket. The existing HID ballast and igniter must be removed or wired around before the lamp goes in, and that's electrician work in most commercial fixtures. If you want a lamp that drops into a working ballast with no rewiring, you're looking for a Type A (ballast compatible) lamp instead, not this one.

5000K is daylight white, the color most commonly specified for warehouses, shops, parking structures, and service areas because it reads clean and keeps contrast high. If the rest of your building is on 4000K neutral white, a 5000K lamp will look noticeably cooler beside it, so mixing the two in the same sightline is visible. The S49392 also runs 80 CRI, which is standard for task and general industrial lighting but below what you'd want for color matching or retail merchandise display.

Two things decide it, and both are physical. First, the socket: this is a medium base lamp, so any fixture with a mogul socket needs a socket change or a different lamp. Second, the wiring: as a Type B ballast bypass lamp it will not operate through the existing HID ballast, so every fixture you relamp has to be rewired to line voltage first. Once those are handled, the 36W, 5000K, 80 CRI combination is consistent lamp to lamp, which is what you want when you're trying to keep one part number across a fleet of openings.

Economy Hi-Pro is Satco's value tier of HID replacement lamp. It's aimed at straightforward relamping where you want the wattage cut and the maintenance interval stretched without paying for the higher output or feature options in the standard Hi-Pro range. The S49392 is a 36 watt, 5000K, 80 CRI, medium base, ballast bypass lamp, which is the basic combination for a general purpose retrofit rather than a spec-driven one.
