What is the beam angle of a searchlight?

The beam angle of a searchlight refers to the width of the light beam it produces. It is typically measured in degrees and can range from narrow spot beams to wide flood beams. The choice of beam angle depends on the intended use of the searchlight.

Narrow Spot Beams:Narrow spot beams have a narrow beam angle, typically less than 10 degrees. They produce a concentrated beam of light that can illuminate distant objects with great intensity. These beams are ideal for long-range navigation, search and rescue operations, and signaling.

Wide Flood Beams:Wide flood beams have a wider beam angle, typically 30 degrees or more. They produce a broader beam of light that can illuminate a wider area. These beams are suitable for illuminating large areas, such as docks, decks, or workspaces.

Considerations when choosing beam angle: Intended use: Determine the primary purpose of the searchlight. Narrow spot beams are better for long-range illumination, while wide flood beams are better for illuminating larger areas.

Distance of illumination: Consider the distance at which you need to illuminate objects. Narrow spot beams are better for illuminating distant objects, while wide flood beams are better for illuminating closer objects.

Area coverage: If you need to illuminate a wide area, choose a searchlight with a wider beam angle. If you need to focus on a specific object, choose a searchlight with a narrower beam angle.

Here’s a summary of typical beam angles and their applications: Narrow spot beam (less than 10 degrees): Long-range navigation, search and rescue, signaling

Medium beam angle (10-30 degrees): General navigation, all-purpose search and rescue, security

Wide flood beam (30 degrees or more): Illuminating large areas, docks, decks, workspaces
