Cree Launches LED Product Characterization Tool

(2009-03-16)

(16 Mar 2009  CREE.COM)

Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, launched the Product Characterization
Tool, an interactive LED design tool that simplifies the task of translating nominal LED performance to
real-world conditions.

The online tool, accessible via www.cree.com , allows users to easily characterize any XLamp® LED
over a wide range of operating conditions, including drive current, flux bin, price and junction
temperature. It also calculates metrics such as lumen output, lumens per watt, lumens per dollar and
more.
Cree’s Product Characterization Tool (PCT) introduces advanced functionality not commercially
offered by any other LED supplier. PCT can perform simple LED system design based on a target
total lumen output, calculating parameters such as number of LEDs required and total system efficacy.
The calculated system parameters take into account electrical, optical and thermal losses associated
with LED system performance. In addition, PCT allows users to compare up to three different XLamp
LED configurations at once, empowering customers to best choose between the industry-leading
XLamp XR, MC and XP package families.

"The Product Characterization Tool acts like an interactive data sheet, giving users a more intuitive
way to design LED systems using XLamp LEDs," said Paul Thieken, Cree, marketing director for LED
components. "Determining even basic LED system parameters like efficacy with only data sheet
graphs and characteristics used to be a time-consuming process. Cree is moving the LED lighting
industry forward by simplifying the process to just a few clicks of the mouse."

More information, including login instructions for the Product Characterization Tool, can be found at
