Additional Guidance

  • Workplace Lighting Balance:
    Modern guidance (as noted in the CIBSE Journal article) emphasizes balancing ambient and task lighting. For example, ambient office areas are typically maintained at 300โ€“500 lux, while specific task areas (such as drafting or detailed workstations) may require 750 lux or more.

  • Important Note:
    These figures are recommended guidelines. Actual requirements may vary based on local standards, specific building use, and individual project needs. Always consult with a lighting designer or engineer to tailor solutions for your circumstances.
