Color specs can waste budget or create patchiness when written badly. Use a practical method: define the use case, select one baseline CCT, set a sensible CRI target, and enforce consistency with batch control.
Answer: Write CCT/CRI specs by use case: choose one baseline CCT and a sensible CRI target, then enforce consistency across poles and batches with documentation and change control. Avoid disputes by adding a commissioning acceptance note and mismatch log procedure—so ‘color’ is verifiable, not subjective.
Key takeaway #1: Consistency is usually more important than chasing extreme CRI numbers.
Key takeaway #2: Mixed CCT across poles/batches creates patchiness and complaints.
Use this guide when writing tender specs for stadium or training-field lighting and you want a professional, defensible CCT/CRI requirement without over-engineering.
