COLOR KINETICS AWARDED U.S. PATENT FOR CHROMACORE™
Company's Core Technology for LED-based Color-Changing Lighting
Sets the Standard for the Digital Revolution

BOSTON — January 25, 2000 — Color Kinetics Incorporated, the pioneer of full spectrum digital lighting, today announces the awarding of a U.S. Patent, which is the first issued patent in its field, for its exclusive Chromacore™ technology. The patent, #6,016,038, covers Stand Alone and network control of multiple LEDs (light emitting diodes) for illumination and display. Chromacore uses microprocessor-controlled multi-colored LEDs to generate over 16.7 million colors and a variety of color-changing lighting effects.

In contrast to conventional lighting techniques, which require gels, dimmers and moving parts to produce color and colored lighting effects, Chromacore generates colored light by using a microprocessor and additive color mixing. In addition, Chromacore technology offers an ultra-long source life of 100,000 hours. It uses little power, produces virtually no heat or UV emissions, and creates dynamic changing color without moving parts, all of which significantly extends the range of environments in which colored lighting effects can be used. Powered by Chromacore, Color Kinetics' line of digital color-changing lighting products are today in use by a veritable "Who's Who" of the retail, design and entertainment industries, including Disney, Sony Loews, Limited Too, Brookstone, Nine West, Saks Fifth Avenue and Harrods, to name just a few.

Chromacore is an integral part of Color Kinetics' growing intellectual property portfolio, which includes U.S. and international filings encompassing a number of emerging digital technologies. In related news today, Color Kinetics announced that it has completed a $13-plus million round of financing that, in addition to strengthening its leadership in the full spectrum digital lighting space, will enable Color Kinetics to expand its intellectual property research and actively extend its digital technologies into new markets. (see press release dated 1/25/00, "Color Kinetics Closes Third Round of Financing")

"Our patent is a major milestone for Color Kinetics, capping over two years of industry recognition for Chromacore and the virtually unlimited applications it enables," said George Mueller, President and CEO. Mueller sees a wide range of applications for Color Kinetics technology, "beyond even the ways that our customers use it today," he said. "The inherent benefits of Chromacore make it possible to incorporate color and light into so many other intelligent technologies, which is what makes this patent significant not just for Color Kinetics, but for the digital market space as a whole," stated Mueller. "We are thrilled to have Chromacore officially acknowledged as a revolutionary innovation and as an technology that Color Kinetics has conceptualized, developed and brought to market, and we look forward to creating, marketing, selling and licensing a host of Chromacore-based digital lighting products."

Color Kinetics co-founders Mueller and Chief Technology Officer Dr. Ihor Lys are named as inventors on the patent. Both are graduates of Carnegie Mellon University, and both are continuing to lead the development of exciting new technologies that will further advance Color Kinetics' mission to create a more bright and colorful world.
