IES G-2-10

The aim of this Guideline is to provide lighting and
design professionals a general understanding of
LED technology as it pertains to interior and exterior
illumination, as well as useful design and application
guidance for effective use of LEDs. Specifically, the
guideline addresses:

• LED technology and lighting performance;
• key differences in measurement methods for
  LEDs compared to traditional sources;
• attributes unique to LED that may provide
  advantages over traditional light sources in some
  applications
• LED application challenges that should be
  evaluated to ensure successful lighting designs
  and promote end-user satisfaction.
• Task based design guidance for general lighting
  applications, as well as specific space and
  building types where LED technology can be
  effectively applied.

Note that LEDs are frequently used to provide color
accents and color-changing effects for indoor and
outdoor lighting; however, these established applications
are outside the scope of this document.
