Beam Angle Explained

Reflector bulbs are more than just floodlights and spotlights. Like any light bulb, they come in shapes and technologies to fit any application. Two cases in point are the PAR and the MR16. These common bulbs, whether halogen, CFL, or LED, are highly specified, containing engineered surfaces that control the beam of light to an angle so precise it takes seven different classifications just to explain their possible uses!

What Is Beam Angle and Why Is It Important?  

Beam angle refers to how widely light spreads from a lamp or fitting. A narrow beam creates focused, concentrated light, making it ideal for highlighting displays, architectural features or specific work areas, while a wider beam provides broader and more even illumination for larger spaces. Choosing the right beam angle is essential for achieving the correct light coverage, ambience and performance in residential, commercial and industrial applications.
