Cree Product Characterization Tool (PCT)

Cree Product Characterization Tool (PCT) ThumbnailIdentifies the best Cree Xlamp LEDs for your design
The Cree Product Characterization Tool (PCT) allows you to select from multiple lighting-system design parameters to compare up to three LED models simultaneously to help in making critical design choices.

For all valid LED drive currents, the PCT quickly and easily does the following:

  • 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
