Why do some LED bulbs have 120 Degree beam angles?

LED lamps that have beam angles in the 120 degree range are designed to disperse the light as much as possible in the same manner as traditional incandescent and fluorescents. LED lamps with a 120° beam angle are designed for lighting under cupboards, small rooms or where the ceiling height is low. They can also be used in most applications when replacing incandescent and fluorescent lamps.
