June 24, 2008... The EPA outlined the basics of its LED module standards in a teleconference today. The EPA spokesperson explained that full-fixture photometry is not practiced for indoor residential lighting. The EPA sited the example of a light source that is often put into a mica or alabaster fixture to produce the right ambiance in residential indoor lighting. The EPA spokesperson said that the organization wanted a set of lighting standards that was technology independent. The EPA indicated that the goal of its guidelines is to allow designers to (at least some extent) directly compare LED lighting to incandescent, fluorescent, or compact fluorescent light sources. For this reason the organization reportedly chose to create standards at the light engine level, not at the fixture level.

The EPA defined the light engine as a packaged LED, a driver (rather than a ballast), and an incorporated heat sink. The light engines would be required to have 50 lm/W or higher efficacy for an uncovered LED light engine or 40 lm/W or higher for a covered LED light engine.
