Collection: Standard Type A LED Light Bulbs

The difference is in their size (diameter). Both use the standard E26 medium screw base, making them electrically compatible.

A19: The standard size (2.375" wide) used for general room lighting in most table lamps and ceiling fixtures.

A15: A smaller size (1.875" wide) specifically designed for appliances (like refrigerators) and enclosed ceiling fan fixtures where the A19 would be too wide.

Interchangeability: An A15 will always fit where an A19 fits, but you can only replace an A15 with an A19 if the fixture has enough physical space.

The A-shape is the standard because of its design and omnidirectional light output.

Omnidirectional Light: The classic pear shape allows the light to radiate in all directions (360 degrees), making it perfect for ambient (general) lighting in rooms.

Universal Base: They universally utilize the E26 medium screw base, which fits over 90% of household sockets, simplifying replacements.

Yes, but you must check the packaging for the "Enclosed Fixture Rated" designation.

Outdoor/Enclosed Use: Standard LED bulbs generate less heat than incandescents, but an enclosed fixture traps heat. If a bulb is not rated for an enclosed fixture, the trapped heat can shorten its lifespan significantly. Always look for the "Enclosed Fixture Rated" label for outdoor porch lights, sealed ceiling fixtures, and garage door openers.

The most common LED equivalent for a standard lamp is the 60-Watt Equivalent, which provides around 800 lumens. To make the best choice, keep these equivalencies in mind:

For Standard Reading/General Lighting, you are typically replacing a 60W bulb. You need an 8-10W LED to achieve approximately 800 lumens.

For High-output Task Lighting or brightly illuminating a large room, you are typically replacing a 100W bulb. You need a 13-15W LED to achieve approximately 1600 lumens.

Always match the lumen output of your old bulb, not the wattage, to ensure the new LED bulb is bright enough.

Yes, A-type bulbs are available in both finishes to control light diffusion:

Frosted: Provides soft, diffused, shadow-free light, ideal for vanity bars, general ceiling lights, or reading lamps where you don't want to see the filament.

Clear: Used to showcase the internal LED filament (Edison-style) for decorative fixtures or to provide a slightly crisper, more focused light.
