The Emess and the EFI torchieres more than lumen-match the halogen torchiere while providing a four to five fold
increase in efficacy. Additionally, these energy efficient torchieres provide switchable dimming options that do not
significantly diminish efficacy, as found with the halogen torchieres. The Emess and EFI torchieres demonstrate to
consumers and the lighting industry that a safe and energy efficient alternative to halogen torchieres can be
economically produced while matching or improving upon the photometric performance of the luminaire.
The development, technology transfer and commercialization of the first generation of energy efficient torchieres
into the market place involved a variety of industry, government and university outreach programs. The following is
a brief history of the essential activities associated with this transfer program.
Initially, research efforts at LBNL were focused on establishing a vision for market transformation programs related
to residential lighting. This required moving state and federal lighting programs away from the short-term
approaches offered by screw-based CFL initiatives to a longer-term solution offered by dedicated (pin-based)
compact fluorescent fixtures. It was realized that the best way to overcome the technical, institution, and consumer
barriers was to develop attractive, high efficiency dedicated fixtures that were designed explicitly for pin-based
In the early to mid 90s, this vision led to a research effort that concentrated on the development of an entire range of
dedicated CFL fixtures and technologies. The intent of this effort was to show, through example, that high quality,
high performance fixtures could perform as well as or better than incandescent technology. A partial objective of
these studies was to convince various government agencies and utilities that dedicated fixtures were indeed the best
option to obtain long-term market transformation.
Close contact with the lighting industry, including lamp, ballast and fixture manufacturers, was critical in every
phase of this initiative for dedicated CFL fixtures. Educating and encouraging communication within the lighting
industry still remains a critical function since most residential fixture manufacturers have little or no knowledge of
CFLs, ballasting, optics or integration issues associated with these new sources.
LBNL's dedicated fixture research development efforts concentrated on the most popular and high use luminaires in
the home. These fixtures included recessed downlights, portable table and floor lamps (torchieres), surface mounts,
and exterior fixture types.
The primary methodology in developing market entries and technology transfer involved:
" fundamental development of advanced high efficiency fixture geometries
" development of technical information on fixture performance
" dissemination information and research findings through conferences and seminars
" development of technical papers
" involvement in industry interaction
All of the material that is developed in the energy efficient fixture laboratory is public in nature. Furthermore, the
objective of the laboratory is to make this material available rapidly to the industry via publications, industry
seminars and seminars conducted at utility and government agencies. The vast majority of the industry partnerships,
transfers and market entries have occurred as a result of these public forums.
The development, transfer and commercialization of the energy efficient torchieres were reflective of this diverse
technology transfer effort. Currently there are three to four manufacturers with products that have interacted with
LBNL on torchiere and fixture development issue associated with the use of CFLs. Because of LBNL's efforts to
encourage technology transfer from the lab to the manufacturing community, the United States will see number of
other small and large manufacturers enter the market which have had direct involvement with the lab. For example,
one of the larger portable fixture manufacturers employed a fixture geometry that was based on one of our earlier
prototype efforts as a pin-based replacement for torchieres. The high performance fixture was their first market
entry and has seen extensive use on college campuses.
In another example, LBNL worked with senior management of the one of largest importers and manufacturers of
torchieres in this country on the evolution of their first energy efficient product. The interaction with this particular
manufacturer was conducted over the telephone and involved advice, guidance and preliminary assessment on how
Here’s what’s next.
