A21 LED Bulbs
A21 LED bulbs are engineered to deliver exceptional brightness and high-lumen output for table lamps, floor lamps, and larger commercial fixtures. While similar in shape to the standard A19, the slightly larger A21 housing allows for more powerful illumination, making them the ideal energy-saving replacement for high-wattage 75W to 150W incandescent bulbs.
We offer a selection of high-output A21 LEDs that feature smooth, dimmable performance and superior color accuracy across multiple color temperatures. Built for durability, these fixtures include shatter-resistant lenses and UL ratings for damp or wet environments, ensuring reliable, long-term performance for both demanding interior spaces and covered outdoor applications.
Technical Performance: Why Choose A21?
The A21 form factor is the professional's choice for areas that require more light than a standard household bulb can provide.
Maximum Lumen Density
Our A21 LED bulbs can produce upwards of 2,600 lumens. This makes them perfect for large open-concept rooms, high-ceiling foyers, or commercial workspaces where a standard A19 bulb would leave dark corners.
Advanced Heat Dissipation
Because high-output LEDs generate more heat, the A21 shape provides a larger surface area for cooling. This thermal management ensures the internal driver stays cool, extending the bulb's life to 25,000+ hours even under heavy use.
Versatile Mounting and Durability
Shatter-Proof Design
Unlike glass incandescent bulbs, our A21 LED replacements utilize high-impact polycarbonate lenses. This shatter-resistance is critical for food service environments, workshops, or any area where safety is a top priority.
Outdoor and Damp Rated
These bulbs aren't just for the living room. Many of our A21 options are UL Listed for damp or wet locations, making them an excellent choice for enclosed porch lights, post top lanterns, or garage fixtures that may experience moisture.
