What do You Need to know about Beam Angle?

A lamp’s beam angle is the angle at which light is spread or emitted. When a ceiling light fixture is switched on, the beam angle is the angle of light that spreads across the floor. A beam spread is another name for it. And having the proper beam angle may provide your building with the right ambiance and visibility.

Halogen lights (and certain LEDs) are available in a range of angles ranging from 4 degrees to 60 degrees, with some of the bigger halogen lamps reaching 120 degrees. Light sources can be classified as having a narrow angle of 5 – 45 degrees or a large angle of 45 – 120 degrees.

What is Narrow Angle and Wide Angle

First and foremost, let us define the terms narrow angle and wide angle. If the location is inside, the beam angle should be chosen based on the ceiling height. If the location is outdoors, the angle should be chosen based on the height of the pole or the height of the location. According to the surface to be lighted, wide angle light sources should be favored at low points and narrow angle light sources at high places.

If a wide angle lighting fixture is placed at a high position, the light will evaporate before reaching the bottom. As a result, it will not offer enough light. If, on the other hand, a narrow angle lighting fixture is placed at a low position, it only lights a tiny area. There will be dark patches, and you will be unable to establish uniform lighting.

How to Choose Beam Angle for LED Lights

The primary issue when selecting the beam angle of LED lights is to ensure that the space to be lighted can be illuminated. In truth, there are several elements to consider while lighting a room.

1. Type of Structure

You must determine how many lighting fixtures you will require in the structure. Then you may select the proper beam angle. Because the beam angle might impact lighting and visibility depending on the height of the ceiling.

2. The Number of LED Lights

A business facility requires 70 lumens per square foot, according to industry standards. You must ensure that you create a lighting layout design plan before selecting the beam angle of LED lights for any lighting project.

3. The Height of Ceiling

Checking the height of our ceiling ensures that the beam angles overlap. Otherwise, you risk having a gloomy, dull section in your building. Overlapping beam angles guarantee that light covers your whole environment and prevents potential injury.

Overlapping beam angles guarantee that light covers your whole environment and prevents harm.

A normal ceiling height ranges from 7.9 to 8.9 feet. As a result, a larger beam angle of 60 degrees or more should suffice. If your ceiling height is greater than 8.9 feet, you will want a narrow beam angle of less than 45 degrees.

4. Type of LED light bulb

Depending on the application, you must select a certain type of LED bulb. The higher the light fixtures in an industrial environment with high ceilings, the narrower the beam angle required. The beam angle will be broader for the lower ceiling.

Beam angle of LED bulbs:

• LED spotlight: 15°-90°

• LED downlight: 30°-60°

• LED flood light: 120°-150°

• LED tube light: 120°-160°

• LED spotlight: 15°-90°

• LED corn light: 180°-360°
