[[File:Cree_xr-e.jpg|thumb|Cree XR-E LED]]Introduced in the Fall of 2006 the XR-E is 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. | [[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 is 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.
