A large multi-die emitter available in 6-volt and 12-volt versions.

Same 5mm x 5mm size as the [[Old Cree LEDs#XM-L|original XM-L]] but with up to 20% more output. Introduced in December 2012. Like the XP-G2, the XM-L2 is silver on top, has two bonding wires, and the die has dots instead of lines. The XM-L2 is significantly larger than the XP-G2 and has a round hole at the upper left as opposed to the XP-G2's square hole. The LEDs are binned at 85°C, so the values shown below have been increased by 13.7% to make comparisons with other LEDs binned at 25°C easier. The first production lights to feature the XM-L2 were the [[ThruNite]] Catapult V3 and TN31 in January 2013, followed by a number of Xeno lights which also had options for neutral tints in Feburary.

Introduced in September 2012, this redesign is similar to the XP-G2. Cree claims up to 20% more output than the [[Old Cree LEDs#XP-E|original XP-E]] at half the cost in terms of lumens per dollar. Given the small die size, this LED throws well for the amount of output. It was used in some smaller Fenix flashlights.

The XP-E2 is binned at 85°C, but for ease of comparison, the output numbers below are increased by 16% to get 25° values.

Introduced in July 2012, the XP-G2 is an all new design with the same size as the [[Old Cree LEDs#XP-G|earlier XP-G]]. Like Cree's other 2012 offerings, the XP-G2 is binned at 85°C, but for ease of comparison, output shown on this page is increased by 13% to get 25° values. In August 2012, [[Foursevens]] was the first company to adopt this LED, claiming up to 20% more output and a 5% smaller hotspot for greater throw compared to the same models using a XP-G.
