3-Way A21 4000K E26d Base 120V LED Light Bulb by Satco Lighting

The Satco Lighting 3-Way A21 LED Light Bulb brings adaptable, high-efficiency lighting into your home with an easy-retrofit form factor. Built with a standard medium double-contact (E26d) base and running on 120 volts, this bulb smoothly replaces traditional 3-way incandescent bulbs. Its three selectable brightness levels - 5W, 14W, and 20W - offer versatile illumination options that suit a range of applications, from ambient lighting to bright task-oriented settings, in table lamps, floor lamps, or any fixture compatible with a 3-way bulb.

With a crisp, neutral 4000K color temperature, this LED bulb offers a clean and balanced light quality - straddling the line between warm and cool tones. This makes it especially ideal for spaces like kitchens, home offices, laundry rooms, or garages, where clarity and accurate color are as important as comfort. At its brightest setting, the bulb produces up to 2150 lumens, delivering ample light for detailed work or everyday tasks. Its broad 220-degree beam spread ensures even coverage across the entire area, minimizing shadows and dark spots.

Despite its powerful illumination, the Satco A21 LED maintains superior color accuracy with a 90+ CRI, ensuring that colors appear vibrant and true-to-life. Although not dimmable, each brightness level shifts smoothly with no flicker, providing reliable and stable lighting. Offering a blend of energy efficiency, functional range, and clean cool white style, the Satco Lighting 3-Way A21 4000K LED Light Bulb stands as a smart, modern upgrade from traditional incandescent or CFL options.
