Beam spread, or beam angle, measures the spread of light (the width of the beam) from a reflectorized light source. The beam spread number is important to know when deciding how much light you want displayed on an object, a sign, or on your floors.
Knowing the beam spread number also helps you purchase the right light bulbs for the desired lighting effect you want.
Spot Beam vs. Flood
Reflector lamps have either a spot or flood beam depending on their size. The difference between a spot beam and a flood is the width of the beam, or the beam spread. Having both styles gives
you more lighting options throughout your property.
