Collimated vs. Directional Lights?

2025.07.30

Is Collimated Light the same as Directional Light?

 Yes, Collimated Light is a high-precision type of Directional Light.

Standard LED directional lights have ~±5° parallelism. For higher precision, use Laser sources (±0.5°).

Conclusion: Collimated = High-precision Directional; but Directional ≠ Always Collimated.
