The past 10 years has seen
a significant advancement in technologies associated
with HID lamps. This includes the incorporation of ceramic
lamp envelopes and the ability to construct lamps with
very exact dimensions. Consequently, the wattages of
HID sources have been reduced to a level competitive
with energy efficient older point-source technologies
such as incandescent and halogen lamps in applications
such as retail and commercial spaces.
Magnetic
ballasts have traditionally ballasted the HID lamps.
Electronic ballasts have been available but have not
made a significant penetration in the market partially
due to size, cost and efficiency. Recent developments
in electronic circuitry suggest that these barriers
have been overcome. Additionally, this new ballast technology
can now provide variable light control so that additional
savings are now available from dimming control.
These
technologies are new to the market and are not being
readily adapted by luminaire manufacturers due to the
uncertainty in proven performance. To date there has
been no independent study of the performance of these
new systems, aside from manufacturers claims. Lawrence
Berkeley National Laboratory has the equipment and expertise
to evaluate these systems and to assist in quantifying
the benefits of the technology for the marketplace,
as it demonstrated in previous work with electronic
ballasts for fluorescent lamps.

Once the manufacturers
claims can be verified, market transformation programs
can be developed to accelerate their adoption by original
equipment manufacturers and end users.
