MFL, WFL, and NSP refer to three types of light beam spread, or the nature of the distribution light produced by a lamp. Deciding between the three types of beam spread will depend upon the type of light spread you need.
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.
Please see the beam angle classification below
|Description||Code||Typcal MR16 Beam Angle||Typical PAR Beam Angle|
|Very Narrow Spot||VNSP||<7 degrees||<15 degrees|
|Narrow Spot||NSP||5-15 degrees||15-30 degrees|
|Spot||SP||16-22 degrees||30-60 degrees|
|Narrow Flood||NFL||23-32 degrees||60-90 degrees|
|Flood||FL||32-45 degrees||90-120 degrees|
|Wide Flood||WFL||45-60 degrees||120-160 degrees|
|Very Wide Flood||VWFL||>60 degrees||>160 degrees|
