EXECUTIVE SUMMARY
On November 15, 2005, the U.S. Department of Energy (DOE) held a High Intensity
Discharge (HID) Lighting Technology Workshop to examine the current state of HID
technologies and identify research and development (R&D) opportunities to enhance the
performance, efficiency, and use of HID technologies in commercial lighting
applications. Thirty-four HID technology experts gathered in Arlington, Virginia to
present papers and participate in open dialogue to help identify the potential of HID
technology.
The goal of the Workshop was to identify the current state of HID technology, including
the current technical challenges, past R&D efforts, and opportunities to improve HID
lighting capabilities for wide-spread adoption in commercial buildings. Specific
objectives to help achieve the goal were: 1) gather input from experts in attendance, 2)
identify cutting edge R&D efforts and challenges, and 3) identify existing metal halide
(MH) performance and improvements that can be achieved within five to ten years,
which would yield significant energy savings and increased market penetration. To
achieve these objectives and the overarching goal, the attendees were asked to focus on
science and engineering advances while considering new interior and exterior
applications for HID technologies.
The workshop format was highly interactive. The morning sessions consisted of paper
presentations from leading HID experts in industry and academia. The afternoon session
was an open roundtable discussion led by a professional facilitator. The combination of
prepared papers, prepared discussions, and open discussions supported the workshop
objectives and provided valuable information that demonstrates the energy savings
opportunity for HID, and specifically MH.
According to DOE’s U.S Lighting Market Characterization Report, HID lighting holds
significant opportunities to contribute to national energy savings. The paper presenters
and attendees feel that MH holds the most opportunity to realize these energy savings.
The prepared papers gave significant information on the current state of technologies and
research. The discussions provided additional detailed information on what research is
needed to overcome technical barriers and achieve increased performance and adoption
of MH technology.
In addition, new research tools and methods were presented and discussed. These new
tools and methods have recently become available in the past few years and offer an
opportunity to provide analysis of the arc tube plasma and chemical fill that has not
previously been possible. These new analytical tools allow the scientists to gain a deeper
understanding of the performance inside the arc tube and analyze different chemical fills.
Table ES-1 below lists the potential for MH lamp performance based on the attendees’
expert opinions. These potential performance improvements are significant compared to
the current state of technology, but are only achievable by overcoming the existing
technical barriers such as restrike issues, color shift, improving color rendering and
reducing source size. The attendees feel these improvements, resulting in marketable
products and energy savings, are achievable within the next five to ten years. However,
