Nomenclature and Definitions for Illuminating Engineering [RP-16-10]
In any industry, all players benefit from speaking a common language. Consistency when we write and talk about lighting eases communication between the diverse roles we occupy in the field, and serves to strengthen our standards and real-world practice. The IES Board of Directors believes that all of our members, and the general public, should be able to reference the most authoritative vocabulary whenever and wherever they need it. Toward the goal of encouraging common understanding, the IES has launched a free, online version of ANSI/IES RP-16-10, Nomenclature and Definitions for Illuminating Engineering. RP-16-10 is the essential source for lighting terms and definitions, as well as information such as conversion factors, equations and standard symbols. The terminology pertains to a wide range of subjects, from vision science and testing procedures to interior and exterior lighting applications.

The web-based format of RP-16-10 allows for an easier and faster research experience than print or PDF versions. Users can browse terms alphabetically or according to the document’s original chapter structure, which consists of twelve sections organized by subject plus chapters containing tables and references. In addition, the terms and definitions are fully keyword-searchable in this format. This means that users can search by any word and retrieve comprehensive results. Even if you do not know exactly what you are looking for yet, you will be able to find it.
