Lighting Guide

Recommended Light Levels

Cibse & SLL

Cibse is the Chartered Institute of Building Service Engineers

The SLL is the Society of Light & Lighting

As proud members of both organisations when we approach a lighting project we have full access to all of the Cibse Lighting Guides to ensure that your project is compliant to the relevant standards & recommendations.

 

For external lighting calculations for public spaces we also observe the correct classification of lighting for roadways, pathways and public realm areas. 

Below is a general guide which you may find helpful in evaluating your next project. 

Please note that these are guidelines and recommendations, a competent survey and analysis of the requirements should also ways be carried out to evaluate the scope prior to project commencement. 

For more information about recommended lighting levels please contact our lighting design consultant: leonard@domusproject.ie
