Beam angle is simply how wide or narrow a light spreads.

Imagine using a flashlight:
- If the light is tight and focused → small (narrow) beam angle
- If the light spreads out and covers a big area → large (wide) beam angle
Narrow beam angles (10°–30°) produce a focused, spotlight effect.
Medium beam angles (30°–60°) offer balanced lighting for general use.
Wide beam angles (60°–120° or more) spread light over a large area.
Choosing the right beam angle depends on your goal:
- Highlight an object → go narrow
- Light up a room → go wide
