[[File:Cree_xr-e.jpg|thumb|Cree XR-E LED easily identified by the metal ring around the LED]]Introduced in the Fall of 2006 the XR-E was widely used in a number of different flashlights, with cool white, neutral white, and warm white colors available in addition to blue, royal blue, and green. Common bin numbers are P4, Q2, Q3, Q4, Q5, and R2 with increasing output from 80 lumens to 122 lumens at 350 mA and a Vf of 3.3V, but with much greater output available with higher currents. The size is 7 mm x 9 mm and you will often see this referred to as a 7090 XR-E. The die itself was available as the EZ1000 at first and then the smaller EZ900. | [[File:Cree_xr-e.jpg|thumb|Cree XR-E LED easily identified by the metal ring around the LED]]Introduced in the Fall of 2006 the XR-E was widely used in a number of different flashlights, with cool white, neutral white, and warm white colors available in addition to blue, royal blue, and green.

Because the EZ900 can have the same overall output as the larger EZ1000 but in a smaller form, it should provide 23% greater intensity and throw (the EZ1000 is 1 mm square and the EZ900 is 0.9 mm square). | ||
