SATCO Lighting S49676 100W LED HID Replacement, 4000K, Extended Mogul Base, Type B Ballast Bypass, Economy Hi-Pro

Yes. The S49676 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. Leaving the ballast in circuit will damage the lamp. Plan on opening the fixture and rewiring the socket, which makes this a job for a licensed electrician rather than a straight screw-in swap.

At 13,700 lumens it is a lamp-for-lamp replacement for a 320W to 400W metal halide or high pressure sodium HID lamp, pulling 100 watts to do it. Compare delivered lumens rather than wattage, since aged HID lamps in service are often putting out far less than their rated output.

No. The S49676 is non-dimmable. On a dimming circuit you'll get flicker, buzz or early failure. For lots and warehouses, pair it with on/off occupancy sensing or photocell control instead, or choose a dimmable LED retrofit if your control scheme requires step dimming.

4000K is neutral white, the usual choice when you're coming off metal halide and want the space to read clean and bright without the blue cast of 5000K. With 80+ CRI color rendering, signage, labels and vehicle colors stay accurate enough for garages, loading docks, and warehouse aisles. If you're matching existing 5000K heads on the same property, this lamp will read slightly warmer side by side.

It has built-in 4KV surge protection, which covers the kind of switching and line transients common on exterior pole and site-lighting circuits. On sites with frequent lightning activity or heavy inductive switching, many specifiers still add surge suppression at the pole base for an added layer.

The lamp weighs 3.53 lb, which is substantially more than the HID lamp coming out. Check that the socket and its mounting bracket are sound before reinstalling, especially in older pole-mounted or pendant fixtures where a tired porcelain socket may not carry the hanging weight in a vertical-base-down orientation.

The housing is aluminum with a polycarbonate lens section. The aluminum acts as the heat sink, which is why these lamps run best inside an open or well-ventilated fixture; fully enclosed HID housings trap heat and shorten LED life. Polycarbonate resists impact better than glass, a help in garages and dock areas where lamps get knocked.
