Thorlux is closed for the Christmas break and will re-open on Thursday 2nd January 2025. Merry Christmas! 
Access Roads, Car Park and Building Perimeter
Operations will often run during hours of darkness making the lighting essential for employee safety and building security. Mounting positions are not as limited as within the service yard so architectural lighting can be selected to enhance the look of the building.
Spill light and upward light should still be minimised.
For recommended lux levels please see CIBSE : SLL Lighting Guide 1 - The Industrial Environment (2012, updated 2018)
