Cree LED Selector Tool — Ready, Set, Create

The Cree Product Characterization Tool (PCT) allows you to select from multiple lighting-system design parameters to compare up to three LED models simultaneously.

The PCT does the following quickly and easily for all valid LED drive currents:

• Shows all critical LED design parameters, such as luminous flux and efficacy, for selected LED models
• Performs de-rating calculations based on junction temperature (Tj)
• Calculates LED valuations, such as lumens per dollar (lm/$)
• Estimates simple LED design parameters, such as the number of LEDs required and total power consumption

The PCT uses specifications and characteristics from LED data sheets to accurately compare LED parameters with changes in flux, price, and junction temperature. It can compare up to three LED models side-by-side so that you can make critical design choices with confidence.
