SATCO Lighting S9552 3W, LED MR16 LED, 3000K, 40 degree Beam Angle, GU5.3 Base, 12V

Yes. It uses the bi-pin GU5.3 base, the same two-pin socket the low voltage halogen MR16 uses, so it pushes straight into the existing lamp holder. It is sold as a 20W incandescent equivalent, drawing 3 watts and putting out 330 lumens, so relamping a hall or display case of 20W halogens is a straight swap as long as the circuit is still 12V.

Yes, it's an enclosed rated lamp, so a gasketed or fully enclosed fixture is allowed. Burning position is universal too, so base up in a ceiling can, base down in a pendant, or horizontal in a display fixture all work.

The lamp itself is dimmable. The catch on 12V LED MR16s is the transformer, not the bulb: a magnetic transformer with a compatible low voltage dimmer generally behaves, while older electronic transformers sized for a 20W halogen load often won't hold a stable dim at 3 watts. Check the minimum load on the transformer you already have before you relamp a whole run.

It carries a damp location rating, which covers bathrooms, covered porches, and soffits where the lamp isn't hit by direct water. It is not wet rated, so keep it out of open weather and out of shower fixtures that aren't sealed. The lens is clear and lensed rather than open.

Yes, most likely. The 40 degree spread is a flood pattern, better for general downlight in a hallway, cove, or under-cabinet run where you want even coverage without scallops. For a tight pool of light on a painting or a retail display, you want a narrow spot in the 15 to 25 degree range instead.

It's a fixed 3000K warm white with 80 CRI, not color selectable, so what you see is what you get on every unit. 3000K reads warm without going amber, which is the common hospitality and residential-corridor color. If your existing lamps are 2700K they will look noticeably yellower beside it, and 4000K neighbors will look cool and blue by comparison, so standardize a whole room at once rather than mixing.

Each lamp draws 3 watts at 0.250 amps on a 12V circuit, so the load per fixture is small compared to the 20W halogen it replaces. Divide your transformer's rated VA by 3 watts per lamp for the upper count, then confirm the transformer's minimum load requirement, which is usually the limiting factor when you go from halogen to LED rather than the maximum.

No on both. It is not DLC approved, so it won't appear on the DesignLights Consortium qualified products list that most commercial utility rebates draw from, and it is not BAA compliant, which rules it out of federally funded work carrying Buy American Act requirements. It is FCC compliant.

Rated at 25,000 hours. In a corridor or lobby burning roughly 12 hours a day that's on the order of five to six years between relamps, which is the argument for swapping a run of 20W halogen MR16s in a hard-to-reach ceiling. Housing is silver with a clear lens.
