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.
Runtimes and output:
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.
