The bispectral fluorescence colorimeter (BFC) phosphor testing system used by CSA Group enables LED and laser lighting manufacturers to go beyond current IES LM-86 methodology. This equipment provides more detailed and useful information about the excitation and emission spectra of phosphors as well as the degradation of phosphor quantum efficacy over exposure time. Studies of quantum efficacy over temperature can also be performed.

This more robust performance data can help you design superior remote phosphor products.

In this whitepaper we explore:

  • Why better testing is needed
  • How BFC phosphor testing is more precise
  • Using BFC testing for LM-86 test configuration
  • Upcoming effective dates for lighting product standards
