LG7 was created to assist designers, owners and engineers in creating high quality lit environments in which users will both feel happy and be productive. The best way that we can all ensure that this process works is to give feedback on how the guidance is used and applied.

Whilst the guide has been widely reviewed and checked for errors there is always the possibility of gremlins having shifted a few apostrophes about: let us know if you spot any! If you feel that the guidance is not correct or not correct under certain circumstances again let us know.

This will greatly help the Society in producing the next version of LG7 in about five years time.

To make a comment on the guide, to make suggestions for the future guide or to give real life examples of successful (or unsuccessful !) office lighting then please send an e-mail to
