The MC-E is widely used in high-power flashlights like the EagleTac M2SC4, Fenix TK40, iTP A6 Polestar, and JETBeam M1X with advertised output of up to 700 lumens. The color version is in the Quark RGB (with neutral white or cool white available) but although the LED allows mixing of colors, the Quark RGB is switched to one color at a time.

[[File:Cree-xml.jpg|thumb|Cree XM-L LED with 6 yellow strips and 3 brass bonding wires]]Larger die LED announced in April 2010 and first available in November, offering efficiency of 160 lumens per watt at 350mA. Output is 260-280 lumens at 700mA (bins T5 and T6) therefore it is more efficient and puts out more light at any current than earlier Cree LED's. However the biggest improvement to overall output is the XM-L can be driven to 3000mA for 910-975 lumens of output. The LED die is 2mm x 2mm on a 5mm x 5mm substrate with 6 yellow strips and 3 bonding wires as opposed to the XP-G with 4 strips and 2 bonding wires and the XP-E with 3 strips and 2 bonding wires. The first production lights to feature the XM-L were versions of the ThruNite Catapult V2 (first to ship), [[EagleTac]] M3C4, a [[4Sevens]] Quark MiNi, and the [[JETBeam]] M1xm, introduced in December 2010, but budget retailer KaiDomain had LED's and [[P60]] drop-ins as well as P60 lights around the same time.

This LED is used in the Nitecore Defender Infinity, early Quarks (R2, neutral whites used a Q3), the iTP A series EOS and S series lights, EagleTac P100 and T100 series.

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 output bins from R2 to R5. Maximum current is 1500mA and Vf of 3.3V with efficacy of 132 lumens per watt.

The XP-G R5 began widespread use in 2010 after being adopted early by 4Sevens and EagleTac. The R4 was used in limited edition titanium Quarks and some of the latest Fenix lights. S2 bins became available in November 2010 but only in Quark and iTP special edition lights. 4Sevens made 100 MiNi 123's in titanium with S3 bins in December 2010.

[[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. 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.
