Lighting Insight

How to Choose the Right Beam Angle: 15°, 24°, 36° or 55°

A simple guide to matching beam angle with ceiling height, spacing and visual purpose.

Beam angle controls how quickly light spreads as it travels. The correct choice depends on distance, target size, spacing, desired contrast and the number of fixtures.

15° — tight accent

Use for focused highlights, tall ceilings, objects, columns and dramatic contrast. It creates a smaller, more intense pool of light.

24° — controlled focus

A practical accent beam for retail displays, artwork, dining tables and feature surfaces where definition is important without being extremely narrow.

36° — versatile architectural beam

Suitable for many residential, hospitality and commercial applications. It balances spread, intensity and spacing flexibility.

55° — broad distribution

Useful when a softer, wider pool is required or ceiling height is lower. It can reduce scalloping but will usually have lower centre intensity.

Do a real mock-up

Finish colours, wall reflectance, furniture and ceiling height change the result. For important projects, test the actual fixture and optic before finalising quantities.
