LED A-Shape & Specialty Lamps
LED A-shape and specialty lamps are the versatile workhorses of commercial lighting, providing reliable ambient and task illumination for offices, hospitality settings, and healthcare facilities. These lamps serve as high-efficiency replacements for traditional incandescent and CFL bulbs, fitting into standard E26 medium-base fixtures while reducing energy consumption by up to 85%. Designed for the rigors of professional environments, our A-shape LEDs provide instant-on, flicker-free light that eliminates the warm-up periods and maintenance headaches of legacy technologies.
Our collection of commercial-grade LED bulbs includes high-lumen A19 and A21 options, as well as specialty shapes like globes and decorative filaments for front-of-house applications. These lamps are engineered with advanced thermal management to ensure a 25,000 to 50,000-hour rated life, significantly lowering total cost of ownership in facilities with extended operating hours. Available in a range of color temperatures from warm 2700K to crisp 5000K, these shatter-resistant LED lamps provide the durability and light quality required for demanding professional applications without hazardous mercury.
Technical Specifications: A-Shape Sizes and Output
Selecting the correct A-shape lamp requires understanding the relationship between physical dimensions and lumen requirements for different commercial fixtures.
A19 vs. A21 Form Factors
A19 LED lamps are the industry standard for general-purpose lighting, typically measuring 2.375 inches in diameter. For higher-ceiling applications or fixtures requiring more "punch," A21 LED lamps offer a slightly larger 2.625-inch diameter. The larger surface area of the A21 allows for higher wattage chips and better heat dissipation, enabling lumen outputs that can exceed 2,000 lumens, making them ideal for large lobbies and retail sales floors.
Mogul (E39) vs. Medium (E26) Bases
While most A-shape bulbs utilize the E26 medium screw base, some high-output specialty lamps feature the E39 Mogul base. It is critical to verify the socket size in industrial "jelly jar" fixtures or large pendants to ensure electrical compatibility and prevent mechanical failure from over-torquing smaller bases.
Performance Features for Professional Facilities
Omnidirectional vs. Semi-Directional Light
Our commercial A-shape LEDs are designed with an omnidirectional beam angle (typically 220° to 300°). This ensures that light is distributed evenly into the reflector of the fixture, preventing the "dark top" effect common in cheaper residential-grade LEDs. This uniform distribution is essential for maintaining consistent footcandle levels on work surfaces and walkways.
Enclosed Fixture Rating and Duty Cycle
In many commercial settings, bulbs are installed in fully enclosed globes or vaportight housings. We offer Enclosed Fixture Rated (EFR) lamps that are specifically tested to operate in high-heat, restricted-airflow environments. Using a standard LED in an enclosed fixture can lead to premature driver failure; selecting an EFR-rated bulb ensures the lamp meets its full rated life even under 24/7 duty cycles.
