There’s a maximum level of lighting as well as a minimum, people should not be going into an area that is brightly lit then into a less well lit area as their eyes need time to adjust, also there should not be any glare.


Buy yourself the IET Electricians guide to emergency lighting.

Subject: Emergency light over spiral stairs.


A first floor flat has an external spiral steel stairway from the ground to the entrance door. The door opens onto a small platform at the top of the spiral stairway. The flat is to be let.


Would you install an emergency escape light over the door at high level, or half way down from the top of the door to one side of the door, say at eye level,  or at a low level just above the platform. The third option also benefits another escape route from the main house at ground level and illuminates the spiral stairs somewhat.


Note. The sides of the spiral stairs are open except for well spaced spindles. Light can get through the sides.

Hi zoomup, presuming the spiral stairs have been in everyday use for a while, how is it normally lit?

This is a new house for the new owner, and is to be used as a holiday let. The spiral external stairs were lit at night by a remote high level automatic flood light (now faulty and to be replaced) and a high level decorative wall light, both positioned about 7 metres away on an adjacent wall, positioned at 90 degrees to the door over the spiral stairs.

Sorry no pics available. I am not that technically advanced. My Nokia 3310 does not take pics.
