Beam Angles: Why do they Matter?

The beam angle of a bulb is one of the most important aspects to look at. Different beam angles can be used for different applications and can impact the intensity of the light output.

For example, if you want to highlight a certain area, say a small display cabinet, a narrow beam angle would focus the majority, if not all the light output in the chosen area. This will naturally attract a person’s focus into the highlighted area.

Another example would be if you want to flood a room with light, a wide beam angle would be necessary to overlap between spotlights to allow a consistent light out put across the room.

The beam angle is determined by various factors. The shape of the bulb, the type of LED, whether the bulb has reflectors built in (Multi-Faceted Reflectors). Its also worth bearing in mind, that the wider the beam angle, the weaker the light output.
