                                  PRESS RELEASE

                    ADVANCED LIGHTING TECHNOLOGIES ANNOUNCES
           ITS MICRODYN(R) TECHNOLOGY NOW SEEN BY SIEMENS AS ANSWER TO

                      AUTOMOTIVE COLORED LAMP COMPLEXITIES

SOLON, OH, MARCH 30, 2001--ADVANCED LIGHTING TECHNOLOGIES, INC. (Nasdaq: ADLT)
today announced that it has received an order for its patented MicroDyn(R)
Optical Coating equipment from Osram, a 100% owned subsidiary of Siemens.

In addition, Siemens has contracted with ADLT engineers to optimize the optical
coating filter deposited by the MicroDyn sputtering system for automotive lamp
production. The optical coating equipment plus the development work is
approximately $2.5 million. This difficult optical coating must meet the rigid
European DOT standards for color, clarity and uniformity. Extreme environmental
durability is also a mandatory requirement for the film.

Siemens believes that coated lamps will be in high demand by luxury European and
American automotive manufacturers as the trend for modern automotive designs
increases.

Wayne Hellman, ADLT Chairman and CEO commented, "This order is the first of many
that we expect to receive as Siemens, and others, apply this technology to the
growing demand for optically enhanced lamps in the automotive business.

In addition, MicroDyn technology is used by another large lighting company to
apply a coating that enhances the energy efficiency of quartz halogen lamps by
almost 50%. These lamps are used in retail and commercial lighting applications.
The complex coatings on the quartz halogen product must sustain temperatures in
excess of 800 degrees C for many thousands of hours and convert IR energy (heat)
into usable light.

Mr. Hellman commented further, "MicroDyn sputtering is the only commercially
available technology that is capable of applying complex optical coatings to
lamp filament tubes at the high volume, low cost needs of the lighting industry.
Siemens' selection of MicroDyn sputtering means that two of the big three
lighting companies in the world are now using this technology."
