INTRODUCTION
Re: Engineer Tech Bulletins

These Tech Bulletins are provided as a continued service since 1960 to engineering departments, utility standards members and generally interested parties in regard to switching outside lighting by a change in natural light levels.

We have covered a wide variety of subjects over the last 45 years that we have been in the indusrty. Many of the bulletins have become obsolete or irrelevant to today’s marketplace, and these are not included. We like to keep you current, however, if you have a specific subject that is not included, please fax, E-mail or phone your request and we will find our tech sheet that covers that subject.

We appreciate your continued interest and support and we will
continue our efforts to provide you with the best products to suit the situation.
