The Satco 4 Watt B11 LED Filament Bulb brings the timeless warmth of a candle-style bulb together with the efficiency of modern LED technology. Its clear glass construction and wide 300° beam angle make it a natural fit for chandeliers, decorative fixtures, and accent lighting — equally at home indoors or in wet outdoor locations (IP65 rated). Available in four color temperatures to suit your project needs: S21284 (2700K) for a warm, inviting glow, S21285 (3000K) for a slightly crisper, neutral-warm tone, S21286 (4000K) for a clean, bright neutral white, and S12501 (5000K) for a crisp, daylight-balanced output.
At just 4 watts, this bulb replaces a 40-watt incandescent while delivering 350 lumens, and its 90 CRI rendering ensures colors look rich and accurate in any setting. Dimmable via 120V phase-cut controls, it gives you precise ambiance control wherever it’s installed. It’s enclosed fixture rated, operates reliably from -4°F to +113°F, and is rated for 15,000 hours of life — meaning fewer replacements and lower maintenance costs over time. Compliant with FCC, Title 20, RoHS, and UL standards and backed by a 2-year warranty, it’s a dependable, code-compliant choice for commercial, hospitality, and residential projects alike.
