Introduced in Fall of 2008, the XP-E shrunk the XR-E by 80%, now 3.45 mm square. It is available, in white (cool, neutral, and warm), blue, green, amber, red, and red-orange. For cool white, bins are Q3, Q4, Q5, and R2 with output from 93.9 to 114 lumens. Neutral white bins are from P4 to Q4 (100 lumens min) and warm white bins range from P2 to Q2 (87.4 lumens min).

[[File:creexpgr5.jpg|thumb|Cree XP-G R5 LED]]Same size package as the XP-E, but with a larger die. Therefore the resulting beam has a little more flood. It is available in varying tints from R2 to R5. Maximum current is 1500mA and Vf of 3.3V with efficacy of 132 lumens per watt.

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 (an R2 also was made, but it does not appear in the datasheet) with increasing output from 80 lumens to 107 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.
