Very compact LED (the die is mounted on a chip 2.45 mm square opposed to 3.45 mm square for XP series) introduced in February 2012, promising lower cost. Should provide similar brightness to XP-E LED's. First available units were warm white with Q2 brightness bin (at 350mA). Can be driven up to 1000mA.

[[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. | [[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.

Introduced in February 2012, the XT-E has the same size chip as the XP series but seems to have a wider viewing angle for more flood and less throw. Can be driven up to 1.5A and available in bins up to R5 (at 350mA).

Can be driven up to 1.5A and available in bins up to R5 (at 350mA). This is a high efficiency LED capable of 148 lumens per watt at 350mA.
