Function
Lighting is provided to facilitate safe personnel access and egress from the nacelle and tower.
Who supplies them
All parts are standard, with many suppliers, for example Chalmit.
Key facts
Luminaires are frequently fitted to ladders and platforms or in some cases via magnets to
the tower wall to avoid welding on lugs (hence introducing stress concentrations) in tower
wall sections.
In the event of loss of grid, an Uninterruptible power supply (UPS) powers emergency lighting, often a subset of standard lights.
