The packaging does not list the updated information for the XM-L2 LED.  The additional orange and silver sticker on the front of the box that says “Upgrade for Free, CREE XM-L2 U2, 15% Brighter” ensures that you have received the XM-L2 model.

XM-L2 U2 has a 15% increase over XM-L U2

Eagletac took their popular P20A2 and put in the powerful CREE XM-L2 U2 LED for 329 ANSI lumens on max output. A couple of lower outputs and flashing modes are there as well for when you need more (or less) than just a lot of light. Eagletac is great about including accessories, and this is no exception, with a holster, lanyard, diffuser, and spare parts included with every light.

Beam profile: Both XP-G and XM-L P20 models offer preciously machined aluminum reflector coated in light orange peel finish for smooth and highly efficient output beam. XP-G gives a tighter and brighter center spot, while XM-L gives out more light overall and has a bigger center spot.

Operations:

• Fully presses the rear switch for constant on (you can pre-select output with head tighten for turbo output and with head loosen for general output). Slightly press the rear switch for momentary on/off.
• To reach low and hidden strobe mode, loosen the head and follow by tightening and loosening the head to reach the low output mode. Repeat the action to cycle through the strobe-slow blink-S.O.S. modes.
• Turbo boost function: P20 series turns on at maximum output power at turbo boost output mode. The turbo boost output lasts for three minutes and reduces its regulated output by 20% (30% for P20C2 XML) to prolong runtime.
