SATCO Lighting S49673 45W LED HID Replacement, 4000K, Extended Mogul Base, Type B Ballast Bypass, Economy Hi-Pro

Yes. The S49673 is a Type B ballast bypass lamp, so the existing HID ballast has to be removed or disconnected and line voltage wired directly to the socket. It runs on 100V to 277V at 50/60Hz, so it works on either 120V or 277V circuits once the socket is wired direct. If you leave the old magnetic or electronic ballast in the circuit, the lamp will not operate correctly.

Yes, it is an enclosed rated lamp, so acorn, shoebox, and gasketed wallpack housings are fine. It is also rated for damp locations and listed for indoor or outdoor use, which covers covered walkways, canopies, and parking structures. Wet location applications with direct water contact are outside that damp rating.

No. The 45W Hi-Pro lamp is non-dimmable and is not a three-way lamp, so it must be fed switched line voltage only. On a dimming circuit you will get flicker, no start, or early failure. For a dimming spec you need a different lamp or a fixture-level LED retrofit kit.

No, it is not DLC approved, so it will not qualify under rebate programs that require a DLC-listed product. It is Title 24 compliant and FCC compliant, which covers California energy code requirements and radio interference. If a rebate is driving the project, choose a DLC-listed lamp instead.

At 6165 lumens with a 300 degree beam spread, the 45W Hi-Pro is aimed at lower-wattage HID retrofits, and Satco lists it against a 125W incandescent equivalent. Compare lumens to the output of the lamp you are pulling out rather than wattage alone, since an aged metal halide lamp is usually putting out far less than its rating. The 300 degree spread throws light nearly all the way around, which suits downlight shoebox and wallpack housings.

Burning position is universal, so base up, base down, or horizontal all work. That matters on retrofits where the old HID lamp was position-rated and you could not flip it.

The S49673 is fixed at 4000K neutral white with 80 CRI, and it is not CCT selectable. If the rest of your site is 5000K, this lamp will read visibly warmer side by side, so standardize a parking lot or garage on one color temperature. Order the 4000K version only where the surrounding lamps are also 4000K.

Draw is 0.450A at the low end of the voltage range down to 0.162A at the high end, on a 45W load. Use the 0.450A figure for 120V branch circuit loading math and 0.162A for 277V. Rated life is 35,000 hours.

It weighs 1.7 lb, which is more than the HID lamp it replaces in some housings, and the extended mogul base puts that weight further from the socket. In older fixtures with a worn or spring-mounted porcelain socket, support the lamp or replace the socket. Body is aluminum heat sink with a clear polycarbonate lens, in a white housing.
