==XM-L==

Larger die LED announced in April 2010 and first available in November, offering efficacy of 160 lumens per watt at 350mA. Output is 260-280 lumens at 750mA (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 [[EagleTac]] M3C4~~, ThruNite Catapult V2~~, 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.

==XP-C==

A lower current version of the XP-E with a smaller die. Maximum current 500mA and Vf of 3.5V. Bins up to Q4 (100 lumens) in cool white, Q2 in neutral white (84.7 lumens) and P3 in warm white (73.9 lumens).

Looks like the XP-E, but the die has 2 yellow strips and 1 bonding wire instead of 3 strips and 2 bonding wires.
