                                  PRESS RELEASE

  ADVANCED LIGHTING TECHNOLOGIES LAUNCHES ITS 300 WATT UNI-FORM(R)PULSE START
              RETROFIT KIT IN RESPONSE TO RISING U.S. ENERGY COSTS

SOLON, OH, APRIL 3, 2001--ADVANCED LIGHTING TECHNOLOGIES, INC. (Nasdaq: ADLT)
today announced the launch of its 300 watt Uni-Form(R) Pulse Start Lighting
Retrofit Kit to respond to the growing demand for energy saving products.

The 300 watt metal halide retrofit kit saves up to 135 system watts compared to
old 400 watt technology while producing the same light with faster warm-up,
faster re-strike, longer life and superior color uniformity. The 300 watt kit
savings at 6000 hours of annual usage is approximately 810 KWH of electricity.
At $.10 per KWH, the savings equals $81 per year per fixture. A typical
warehouse, big box retailer or assembly operation with 400 fixtures would save
more than $32,000 in energy costs per year. Some parts in the U.S. anticipate
paying up to $.20 per KWH, which could increase the savings to $162 per year per
fixture.

ADLT estimates that the existing industry wide installed base of the 400 watt
metal halide and high pressure sodium lamps is 40 million units. If 20 percent
of this installed base were replaced, the estimated savings to customers would
be approximately $640 million of energy per year at $.10 per KWH.

Wayne Hellman, ADLT Chairman and CEO commented, "ADLT's Uni-Form Pulse Start
products were designed primarily for new installations where this year we expect
to sell approximately $40-50 million. The opportunity exists for a retrofit kit
using this technology to replace much of the already installed, old metal halide
systems. We are launching our kit at a price that will allow a payback in less
than one year for most installations."

 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,
manufactures and markets passive optical telecommunications devices, components
and equipment based on the optical coating technology of its wholly-owned
