LED A19 Bulb 

LED A19 bulbs and LED A21 bulbs are ideal replacement for existing indoor incandescent bulbs. Upgrading to LED is the best way to get energy-efficient lighting that will cost less money and produce less heat. A19 LED light bulbs come in warm white, neutral white, and cool white color temperatures, and can replace up to 100 watts incandescent fixtures. Choose from specific 2700K, 3000K, 3500K, 4000K and 5000K LED A19 and A21 bulbs. The A19 LED light bulb is the standard bulb shape that people associate with the LED light bulb as replacement for an incandescent bulb. It is one of the most common shapes for household bulbs and is great because it is omni-directional, meaning it can spread light in all directions. LED A19 bulbs are dimmable, Energy Star approved, and have up to 5 years warranty.

A19 LED Bulb vs A21 LED Bulb

LED A19 bulbs are available in two shape options, A19 shape bulb or A21 shape bulb. The difference between these two shapes is regarding the diameter of the LED light bulb. The LED A19 bulb has a diameter of 2.4 inches while LED A21 bulbs have a diameter of 2.6 inches. Although this does not seem like a significant difference, A21 bulbs are different than the standard bulb because they are slightly taller and may not be compatible to fit into fixtures as replacements for A-19 bulbs unless the fixture is able to accommodate both sizes. Each LED A bulb can be installed in various fixtures such as ceiling fans or plug-in lamps and some can be a dimmable LED light bulb. 

Dimmable LED A19 and A21 Bulb

Most A style LED bulbs are now a dimmable LED light bulb to accommodate dimmable lamps and fixtures. Dimmable A-19 LED bulbs save more energy by reducing the power consumption and light output, thus increasing the bulb's rate life. LED bulbs are now also used as part of home control systems to control light output and give custom ambiance to different parts of the house. A dimmable LED light bulb is the most versatile in any home. A19 and A21 dimmable LED lights can be used in kitchens, bedrooms, hallways, and basements. LED light bulbs are compatible with most single pole or 3-way dimmers and have much better output compared to an incandescent light. 

Omni-Directional LED A19 Bulb

An omni-directional LED light bulb can cover a wider beam angle compared to a standard bulb, which results in a larger area being lit. LED A19 Bulbs are the best replacement for any fluorescent light or incandescent light. A19 LED bulbs are ideal for omni-directional applications like table lamps, chandeliers and wall sconces to provide light in upward and downward directions. Omni-directional LED lamps provide light in an almost 360° beam angle in all directions, much better than a directional A19 or A21 LED light bulb as well as regular flood or spot LED BR and LED PAR bulbs.
