Products A19 LED Light Bulbs



An A19 light bulb is a general lighting service (GLS) lamp that has an inverted pear shape and is fitted to a medium screw (E26) base. The lamp designation A19 means the bulb has an arbitrary spherical end section tapered to a narrow neck and the diameter of the lamp at its widest point is 19/8 in. or 2-3/8 in. (60 mm). A19 light bulbs have an Edison screw base with a 26-millimeter diameter as measured across the peaks of the thread on the base (male), designated as an E26 or “medium” base. The bulb is approximately 4-3/8 inches (110 mm) in length. A19 light bulbs operate on line voltage (e.g., 120 V).

The designations of A-lamps were created for standardizing the design and construction of light bulbs using incandescent lighting technology. A-lamps have been the iconic household light source since Edison’s invention of the incandescent lamp. A19 lamps, in particular, are the most common general light source in use today. These general service lamps also are used widely in commercial, retail, and hospitality applications. The omnidirectional lamps are relied upon as a general lighting source in light fixtures ranging from wall sconces, ceiling lights, pendant fixtures, table lamps, and floor lamps to recessed downlights.
