What are A19 Bulbs?
A-Shape ("Arbitrary") or general service bulbs are likely the light bulb we are all most familiar with. It's shape is so ubiquitous that this is likely the first form factor you think of when someone says "light bulb". A19 bulbs typically come in outputs ranging from 20 watts up to 100 Watts in their incandescent forms.
Incandescent A-Shape Ban
Starting January 2012, 100 Watt incandescent A-Shape bulbs will not be available for sale in retail. This phase-out will continue and finish with 40 watt bulbs in January 2014.
Much of the progress made over the past few years has been focused on developing and perfecting the A19 LED. The opportunity is enormous with over 6 Billion bulbs in service worldwide.
We offer two primary types of A19 LED Light Bulbs, choosing the right type will ensure the best overall experience/performance: Directional LED A19 and Omni-Directional LED A19.
Directional bulbs are perfect for recessed cans or any place where a directional light source is desired. Their 180 Degree and below beam cut off is perfect for this application as no light is wasted. As a result, they can out-perform their omni-directional cousins with less lumens/power consumption.
This greater efficiency however is sacrificed when they are used in a table lamp or floor lamp that takes advantage of an Omni-Directional beam.
Omni-Directional LED are a recent innovation. For the first time these bulbs allow for the replacement of incandescent lamps with a similar if not identical beam pattern. Omni-Directional LED Bulbs are perfect for table lamps utilizing a lamp shade.
They are however not as effective as directional LED when installed in recessed cans.
