Is there any guidance as to what level of overnight lighting should be provided in an indoor sports hall if this be used for emergency overnight shelter/sleeping after some emergency.
The existing lighting is T8 fluorescent and gives three switch selectable lighting levels, but the lowest of these is clearly very excessive if people are sleeping, whereas total darkness clearly carries risk of trips, falls, and other accidents.
I was thinking about providing two levels, 10 lux initially and then 1 lux. I lux is several times that provided by moonlight and “sounds about right” But is there any better guidance than me thinking “that sounds about right.”
10 lux being provided as an intermediate level between daytime lighting and overnight lighting.
