Understanding the Different Beam Angles of LED Moving Heads


LED moving heads have quickly gained popularity in the lighting industry due to their versatility and ability to create stunning visual displays. One of the key factors that contribute to their effectiveness is the beam angle. In this article, we will delve deeper into the concept of beam angles, their significance in LED moving heads, and how to choose the right one for your specific lighting needs.

I. What are Beam Angles?

A. The Basics:

Beam angle refers to the spread of light emitted from a lighting fixture. It determines the size and coverage area of the light beam projected onto a surface. LED moving heads are available in various beam angles, ranging from very narrow to very wide, allowing users to create different lighting effects.

B. Understanding the Terminology:

To have a better grasp of beam angles, it is important to understand the commonly used terminology associated with this concept. There are two primary angles to consider:

1. Field Angle:

The field angle is the total arc of light emitted by the fixture, encompassing the entire spread of light, starting from the edge of the beam to where the light intensity drops to 50% of its maximum output.

2. Beam Angle:

The beam angle, on the other hand, represents the angle at which the light is emitted from the lens of the LED moving head. It is the measured angle where the light intensity drops to 50% of its maximum output in the center of the field.

II. Different Beam Angles and Their Applications:

A. Narrow Beam Angles:

Narrow beam angles typically range from 5 to 15 degrees. These focused beams of light are highly intense and create sharp, well-defined edges. They are commonly used for highlighting specific elements or creating dramatic lighting effects. Narrow beam angles are ideal for spot lighting applications, such as highlighting a focal point on stage or showcasing a product in a retail environment.

B. Medium Beam Angles:

Medium beam angles usually range from 20 to 40 degrees. They offer a balanced distribution of light, making them suitable for illuminating larger areas without sacrificing intensity. These angles work well for general stage lighting or creating a wash effect on a dance floor. Additionally, medium beam angles are often preferred for architectural lighting, providing adequate coverage for buildings or structures.

C. Wide Beam Angles:

Wide beam angles range from 45 to 60 degrees or more. They provide a considerably broader spread of light, covering large horizontal and vertical areas. This makes them ideal for applications that require uniform illumination across wide spaces. Wide beam angles are commonly used in outdoor events, stadiums, or concert venues to provide even lighting coverage for the audience and performers.

III. Choosing the Right Beam Angle:

A. Consider the Purpose:

Before selecting a beam angle, it is crucial to consider the purpose of your lighting application. Are you aiming for a spot effect, wash effect, or an even distribution of light? Understanding the desired outcome will help you narrow down the appropriate beam angle.

B. Evaluate the Space:

Take into account the dimensions and layout of the area you need to illuminate. Smaller spaces may require narrower beam angles for more focused lighting, while larger spaces might benefit from wider beam angles to cover a broader area.

C. Lighting Design:

Consider your overall lighting design. If you are setting up a stage performance, you may require different beam angles for different scenes or effects. Having a variety of moving heads with varying beam angles at your disposal allows for more versatility in creating captivating lighting displays.

D. Trial and Error:

Sometimes, it may be necessary to experiment with different beam angles to achieve the desired result. Renting or borrowing different moving heads with various beam angles could be a smart move before making a long-term investment.


Understanding the different beam angles of LED moving heads is essential for creating captivating lighting displays and achieving the desired lighting effects. From narrow spotlights to wide floodlights, each beam angle offers a unique way to enhance your lighting design. By assessing your specific application, considering the space, and being mindful of your desired outcome, you can confidently choose the perfect beam angle to create visually stunning and immersive lighting experiences.
