The Beam Angle for a light bulb is the angle in degrees at which the light is distributed. Based on the Beam Angle the lamps are divides in two main categories:
Spots and Floods
Spots refer to light bulbs that have narrow angles. They Spot bulb create a circle of light, also known as a hotspot, with a small diameter, which remains very bright over long distances. Spot bulbs are used in stores to highlight a special area or outdoors to illuminate an architectural feature.
Flood refers to light bulbs that have a wider angle. The flood bulbs illuminate a larger area at a shorter distance than Spot bulbs. Floods bulbs are ideal for general illumination in the home, office, or retail spaces.
