SATCO Lighting S21741 2W MR11 LED, GU4 Base, 3000K, 12V, 36 degree Beam Angle, 2-Card

No. The S21741 is a 12 volt MR11 lamp, so it needs a low voltage fixture with a 12V transformer or driver behind it. Dropping it into a line voltage 120V socket is the wrong application. Low voltage track heads, display cases, and landscape fixtures are where this lamp belongs.

It uses a GU4 bi-pin base, which is the standard two pin base on 12V MR11 halogen lamps. If the halogen you are pulling out has two small pins on 4mm centers, this drops straight in as long as the fixture is fed 12 volts.

The lamp draws 2 watts at 12 volts on a GU4 base, so it fits the same socket as a 12V MR11 halogen and pulls far less current. That lower load matters on an existing magnetic or electronic low voltage transformer, which often has a minimum load requirement and may flicker or not start if the total LED wattage falls below it. Check the transformer's minimum load before swapping a whole run.

36 degrees, which is a flood pattern rather than a tight spot. It spreads light across a display shelf, artwork, or a small retail case instead of punching a narrow accent beam. If you need a concentrated pinpoint on a single object, look for a narrower beam angle lamp.

3000K, a warm white. It sits between the 2700K of incandescent and the neutral 3500K to 4000K range. If the rest of your fixtures are 3000K you will get a consistent look; mixing it beside 2700K lamps in the same sightline will read slightly cooler.

It is packaged as a 2-card, meaning two MR11 LED lamps per card. For a property manager relamping several low voltage heads, count your sockets and order in pairs.
