Cree EasyWhite™ versus Philips Lumileds ‘Freedom from Binning’

Forge Europa Cree GraphA question we are often asked is how do the MacAdam-Step binning regimes of Cree and Philips Lumileds compare? This brief article makes the comparison.

For reference:

• Cree EasyWhite™ binning is made up of a set of 4-Step and 2-Step MacAdam colour bins
• Philips Lumileds ‘Freedom from Binning’ is made up of a set of 5-Step and 3-Step MacAdam colour bins.

The most striking difference, and indeed likely the source of a lot of the questions, is that Cree use a series of quadrants to define their EasyWhite™ colour bins whereas Philips use a set of ellipses as part of the ‘Freedom from Binning’ regime. Plotting quadrants is relatively straightforward using a spreadsheet application; however plotting ellipses and indeed rotated ellipses is a little more involved.
