 ADVANCED LIGHTING TECHNOLOGIES ANNOUNCES NEW FIBER OPTIC LIGHTING FACILITY TO
                      RESPOND TO RISING U. S. ENERGY COSTS

SOLON, OH, APRIL 11, 2001--ADVANCED LIGHTING TECHNOLOGIES, INC. (NASDAQ: ADLT)
today announced that construction has begun at its Solon headquarters of a fiber
development and production center. The project is being managed by Fiberstars,
Inc., ADLT's partner in the development of energy efficient fiber optic
lighting, funded in part from a grant from the Advanced Technology Program of
the National Institute of Standards and Technology, a unit of the Department of
Commerce.

A Uni-Form(R) Pulse Start metal halide light source is the most efficient white
light source known. However, the use of metal halide lighting technology makes
sense at higher lighting levels, or in big spaces such as factories, big box
retailers, and food stores. It doesn't work nearly as well in most common levels
used in commercial and retail buildings. Because of this, many energy
inefficient 100 and 65 watt reflector and 50 watt halogen lamps continue to be
sold each year.

Up until now, these high volume opportunities have been inaccessible to high
efficiency metal halide technology. The possibility of using fiberoptics changes
all that. By channeling metal halide efficiency into fiber optic lighting
systems, the best of metal halide benefits can be used everywhere. Fiberoptics
can provide the "miniaturization" of metal halide by dividing and distributing
the light. Fiberoptics for general lighting is the next major lighting advance.
Using fiberoptics, a 68 watt metal halide arc source, for example, can provide
the light of four 60 watt incandescent bulbs.

Using patents and process technology initiated by Rohm & Haas Corp. and acquired
by Fiberstars last year, work at the new fiber development and pilot production
facility will focus on developing energy efficient metal halide based fiber
optic lighting systems to serve the large retail store lighting market.

Later this year, ADLT plans to expand this facility to incorporate the
high-speed fiber extrusion equipment previously purchased from Rohm & Haas. Mr.
Wayne R. Hellman, ADLT Chairman and CEO commented, "We believe that the Rohm &
Haas equipment represents the finest large cable extrusion process in the world
and combined with the unique miniaturized Uni-Form(R) Pulse Start light source,
it can allow the expansion of energy efficient metal halide technology into the
large commercial and retail market. We believe that fiber optics offers the
potential to expand the usage of metal halide lamps ten times over current
levels."

Mr. Hellman further commented, "In order for the intense metal halide light to
be customized and coupled with the polymer cable efficiently, ADLT had to
develop a unique optical coating to be used as part of the system. The solution
was provided by our unique MicroDyn(R) and IsoDyn(TM) optical coating
technologies at DSI."

Advanced Lighting Technologies, Inc. is an innovation-driven designer,
manufacturer, and marketer of metal halide lighting products, including
materials, system components and systems. The Company also develops,
