Satco Lighting S8737 – Frequently Asked Questions

1) Can the Satco S8737 LED A21 be used on a dimmer switch?
No. The S8737 is a non-dimmable lamp. Put it on a dimmer circuit and you risk flicker, buzz, or early failure. If the fixture is on a dimmer, either replace the dimmer with a standard toggle or spec a dimmable A21 instead. It also isn't a three-way lamp, so it won't step through levels in a three-way socket.
2) Will a 20W LED A21 like the Satco S8737 actually replace a 125W incandescent bulb?
Yes. The S8737 draws 20 watts and is rated as a 125W incandescent equivalent, putting out 2450 lumens at 2700K. The 2700K color is the warm white tone people expect from an incandescent, so the light won't look cooler or bluer than what you're pulling out. CRI is 80.
3) Can I use the Satco S8737 A21 in an enclosed fixture or a closed globe ceiling light?
Yes, it's an enclosed rated lamp, so sealed globes, jelly jars, and closed ceiling fixtures are fine. Many LED A-lamps are not, and running a non-enclosed-rated lamp in a sealed fixture cooks the driver. Burning position is universal, so base-up, base-down, or horizontal all work.
4) Does this 20W LED A21 work on 277 volt commercial lighting circuits?
It does. The S8737 runs 120V through 277V at 50/60Hz, drawing 0.167A at the low end down to 0.072A at 277V. That makes it usable in commercial and multi-family buildings wired at 277V as well as standard 120V residential circuits, so you can stock one lamp for both.
5) Can I put this LED A21 in an outdoor porch light or covered entry fixture?
Yes, within limits. The S8737 is rated for indoor and outdoor use at a damp location rating, which covers covered porches, soffits, breezeways, and enclosed outdoor fixtures. A damp rating does not cover direct exposure to rain or spray, so an open fixture where water hits the lamp needs a wet-location rated lamp instead.
6) Can the Satco S8737 be sold or installed in California?
No. The S8737 carries a Non-Compliant California designation, so it should not be specified for jobs in California. For work in that state, pick an LED A-lamp that carries a California compliant marking. The lamp is also not DLC listed, which matters if your project or utility rebate requires DLC qualified product.
7) Is a 280 degree beam LED A21 wide enough for an open table lamp or a bare socket fixture?
Yes. The 280 degree beam spread with a frosted lens throws light nearly all the way around the lamp, close to how an incandescent behaves, so there's no dark side or hot spot visible in shaded table lamps, sconces, or exposed-socket fixtures. The frost diffuses the LEDs so you don't see individual emitters.
8) How long will these LED A21 lamps last before maintenance has to relamp again?
The S8737 is rated 25,000 average hours. In a common-area fixture burning roughly 12 hours a day that's about 5.7 years before relamping, which is why property managers standardize on a single A21 across a building rather than chasing one-off replacements. Each lamp weighs 0.34 lb.
9) Is the S8737 a color selectable LED bulb?
No. It's fixed at 2700K warm white, with no CCT selection switch. If you need to field-select between 2700K, 3000K, and 4000K on the same lamp, this isn't the one, pick a CCT selectable A21. For a building already standardized on warm white, the fixed 2700K keeps the color consistent from fixture to fixture.
10) Is this LED bulb plastic or metal, and does it look white when it's off?
The S8737 uses a die-cast aluminum and polycarbonate construction, with aluminum serving as the heat sink for the LED driver. The housing is white with a frosted lens, so in an open or exposed socket it reads as a conventional white A-shape bulb rather than a colored or clear lamp.
