SATCO Lighting S49674 54W LED HID Replacement, 4000K, Extended Mogul Base, Type B Ballast Bypass, Economy Hi-Pro

Yes. The S49674 is a Type B ballast bypass lamp, so it wires direct to line voltage and the existing magnetic or electronic HID ballast has to be removed or bypassed first. Leaving the ballast in the circuit will damage the lamp. It runs on 100V to 277V at 50/60Hz, which covers most commercial fixture voltages, and draws 0.540A down to 0.195A depending on where in that range you land.

Enclosed rated, so it can be installed in a closed acorn, post top, or lensed wallpack without voiding the lamp's thermal design. It carries a damp location rating and is listed for indoor or outdoor use, which means covered outdoor spots like canopies, soffits, and parking garages are fine. It is not rated for wet locations with direct rain contact on the lamp.

The S49674 puts out 7,398 lumens at 54 watts, which Satco rates as a 200W incandescent equivalent. In practice that output range is where facilities managers swap out low-wattage metal halide and HPS heads. Compare your existing lamp's delivered lumens, not its wattage, since an aged HID lamp is often putting out far less than its rating.

It is not DLC listed, so it will not qualify for utility rebate programs that require a DLC Qualified Products List entry. It is Title 24 compliant and FCC compliant. If the rebate is driving the project budget, you need a DLC-listed lamp instead.

Burning position is universal, so base up, base down, or horizontal all work. That matters on retrofits where the original HID lamp was position sensitive. The 300 degree beam spread means light is thrown nearly all the way around the corncob body, so the fixture's reflector does the aiming rather than the lamp.

No. The S49674 is a non-dimming lamp and it is not three-way capable. If your area needs step dimming or occupancy-based level control, that has to happen at the fixture or driver level, not through this lamp. Feeding it from a dimmer will cause flicker or premature failure.

The S49674 is fixed at 4000K neutral white with 80 CRI, and it is not a CCT selectable lamp, so there is no field switch to change it to 3000K or 5000K. If your other openings are running 5000K, this one will read noticeably warmer beside them. Standardize the whole area on one color temperature when you spec it.

Rated average life is 35,000 hours. On a dusk-to-dawn parking lot schedule of roughly 4,000 hours a year that is around eight years between relamps, which is the real argument for the retrofit on high-bay or pole-mounted heads where the lift cost exceeds the lamp cost.

Base is aluminum with polycarbonate, the lens is clear polycarbonate, and the housing is white. The aluminum section is the heat path, so it needs air around it inside the fixture. The all-plastic lens means no glass to shatter in a high-vibration location like a garage deck or a loading dock.
