Beam spreads are designated as FL , SP , NSP (narrow spot), and VNSP (very narrow spot), as stamped on the back of the lamp's reflector. PAR38 lamps, with an E22 base and with ratings up to 150W, were often used for domestic outdoor floodlight illumination for patios, backyards, and often combined with a PIR sensor switch as a security ...
The compact size of the MR base allows for much smaller, more discreet fixtures than the incandescent reflector bulbs that pre-dated MRs. The reflector controls the direction and spread of light cast from the lamp. MR lamps are available with different beam angles from narrow spot lights of as small as 7° to wide flood lamps of 60°.
Some LEDs are rated as having a 120° beam angle, [7] directed "up", i.e. perpendicular to the mounting surface. 'Side view' or 'edge emitter' SMDs are designed such that light is emitted parallel to the adhering surface (i.e., 90 degree difference to typical tape design).

Four different beam angles can be obtained on the PAR-64. The beam angle is determined by the lamp. Lamps come in "very narrow" (6° x 12°), "narrow" (7° x 14°), "medium" (12° x 28°), and "wide" (24° x 48°). Each angle has two numerical values since the beams are elliptical rather than circular. PAR 16s are often referred to as "birdies".
Beam lights are often built much like the spot in terms of functionality aside from one key difference: beam lights use a wide lens to make an even more extreme beam. A typical spot has a beam angle from 15 to 35 degrees, whereas an average spot has a beam angle of three to seven degrees with some high end companies producing lights with zero ...

An oblique projection of a focus-balanced parabolic reflector. It is sometimes useful if the centre of mass of a reflector dish coincides with its focus.This allows it to be easily turned so it can be aimed at a moving source of light, such as the Sun in the sky, while its focus, where the target is located, is stationary.
