Checking the lighting installation

1. Scope

  • What should be evaluated? Electric lighting, emergency lighting, daylight conditions, functionality and control, maintenance plan, electrical efficiency, etc.

2. Conditions

  • Regarding the control of new systems, which conditions applied when planning?
  • Evaluation of existing systems?
  • Evaluation with or without daylight?
  • Are the measured values new values or maintained values?

3. Implementation/checks with light measurement

  • Illuminances – mean value/uniformity for the working area, immediate surroundings and the lowest illuminance within peripheral areas.
  • Luminaires’ mean luminances.
  • Calculate where appropriate the UGR-glare index.
  • Luminance conditions in the premises.
  • Luminaire’s cut-off angle.
  • Light sources’ colour reproduction and colour temperature.
  • Perform visual evaluation and interview personnel.
  • Perform a functional check.
  • Check the calibration, burn-in time and prevailing operating conditions before light measurement.
