Collection: Standard Type A LED Light Bulbs

A19 has a nominal diameter of 19/8 inches, or 2.375 inches, while A15 measures 15/8 inches, or 1.875 inches. Both formats are available with an E26 medium screw base, but the smaller A15 body suits compact fan and lighting fixtures. Interchangeability depends on the base, voltage, physical clearance, and fixture rating, not diameter alone.

Type A identifies the familiar pear-shaped bulb family used for general household lighting. The number describes nominal diameter in eighths of an inch, while a separate designation such as E26 or GU24 identifies the base. This collection includes A15, A19, and selected A21 LED formats, so Type A does not mean one universal size or connection.

Enclosed-fixture-rated bulbs are designed for the heat that builds up inside a covered fixture; the collection includes both enclosed-rated and non-enclosed-rated models. Outdoor use introduces a separate moisture requirement, addressed by the lamp’s damp- or wet-location rating. An E26 base or A19 shape does not establish either rating.

A 60W-equivalent LED typically provides around 800 lumens, with examples in this collection using 8–10W. For brighter lighting, 100W-equivalent options provide approximately 1,490–1,600 lumens and use roughly 13–17W across the listed products. Lumens describe brightness, while actual watts describe electricity consumption.

Yes. Frosted bulbs diffuse light across the bulb surface and soften the appearance of the internal light source, making them useful in exposed fixtures and shaded lamps. Clear filament bulbs display the internal LED filaments for a decorative effect; the finish changes the appearance of the light source, not automatically its lumen output.

No. A dimmable bulb varies its output through a compatible dimming control, while a three-way bulb provides separate light levels through a three-way lamp socket. The collection includes three-way A19 models with listed power steps of 3W, 9W, and 12W, which is different from continuously adjusting a standard dimmable bulb.

E26 uses a medium screw base, while GU24 uses a two-pin twist-lock connection. Both can appear on A-shaped bulbs, but they fit different sockets. Base style and supply voltage are separate specifications; this collection also includes a 12V E26 model alongside conventional household-voltage options.

Dusk-to-dawn bulbs use a photocell to respond to ambient light, turning on as the surroundings become dark. Motion-sensor bulbs respond to movement; the collection includes A19 models with PIR sensors. One provides light based on darkness, while the other adds movement-triggered operation.

A fixed-CCT bulb produces one specified white-light color, while selectable-CCT models offer preset choices such as 3000K, 4000K, and 5000K. Smart tunable-white models allow white-light adjustment through their supported controls, and selected RGB models also produce colors. These are different control features, even when the bulbs share an A19 shape.

Many listed models have a rated life of 15,000 hours, preserving the original page’s lifespan reference. Their light distributions vary: listed examples include approximately 280°, 300°, and 320°, rather than every bulb producing an identical 360° pattern. Bulb construction and the surrounding shade or reflector influence how that light reaches the room.
