I was hoping someone would be able to help me with some information I require: What are the minimum/maximum required lighting levels for a Postal sorting/distribution depot? This applies to sorting and office areas.

I have no access to a CIBSE Guide - Code for Interior Lighting, or a HS(G) 38 Lighting at Work, otherwise I would refer to them!

Many thanks
