A 3-watt LED MR11 replacement bulb with a GU4 bi-pin base, delivering 210 lumens of warm 2700K light for accent, under-cabinet, and display lighting in damp-rated locations.
This Satco S9280 LED bulb replaces a 20-watt incandescent while using only 3 watts, saving energy without sacrificing warm light quality. The clear glass envelope and compact MR11 shape make it ideal for track heads, under-cabinet fixtures, and enclosed sconces where a small, focused beam is needed. Rated for 25,000 hours and damp-location safe, it's a reliable choice for bathrooms, covered patios, and kitchens.
Best for
- Under-cabinet task lighting in kitchens, providing warm accent light for countertops
- Bathroom vanity fixtures rated for damp locations, such as enclosed sconces over mirrors
- Display or accent lighting in track heads or small recessed fixtures
- Covered outdoor areas where damp-rated bulbs are required
- Enclosed fixtures where heat buildup is a concern (rated for enclosed use)
Not ideal for
- Open outdoor fixtures exposed to rain or direct water spray (damp-rated, not wet-rated)
- High-ceiling general room lighting where a wider beam angle or higher lumen output is needed
- Fixtures requiring a standard medium (E26) base – this bulb uses a GU4 bi-pin base
How bright is it?
210 lumens – about as bright as a 20W incandescent bulb. This is suitable for accent, task, or decorative lighting, not as a primary room light. Use multiple bulbs in a track or multi-sconce fixture for more coverage.
Light color and feel
2700K warm white – a soft, golden tone similar to traditional incandescent bulbs. It flatters skin tones and warm wood or brass finishes. With an 80 CRI, color rendering is adequate for most residential settings. The bulb is dimmable, allowing you to adjust brightness for mood or task needs.
Sizing and fit
Dimensions: 1.38 inches wide by 1.5 inches tall. This MR11 bulb fits fixtures designed for a GU4 bi-pin base and a compact reflector shape. Always check your fixture's maximum bulb size and base type before purchasing.
