A19 bulbs are standard screw in bulbs designed to be the direct replacement to your existing incandescent and CFL bulbs. Providing the same brightness at a fraction of the energy consumption as your old incandescent bulb, A19 bulbs are the cost-effective alternative. These bulbs feature a variety of color temperatures for any of your lighting needs.
The beam angle of an LED bulb is the angular dimension of the cone of light from the lamp. It encompasses the central part of the beam out to the angle where the intensity is 50 percent of maximum.
For most household ceiling fitted applications, a beam angle of 30 or 40 degrees would be sufficient. For outdoor applications, a wider beam angle of 60 to 120 degrees is preferred to cover a larger surface area.
Color temperatures range from warm white to cool white.

A19 LED bulbs can easily replace a 40W or 60W incandescent bulb.
A good rule of thumb to figure out your LED replacement is to look at the lumens (desired brightness), and find a bulb that works accordingly.
