Not exactly...4sevens is producing a line of Titanium quarks, which come in all the different form factors and interfaces, and use a Cree XP-G R4 LED. They are a limited run and could be sold out now for all I know. I think these are the only, or one of the only, XP-G lights currently in production, because this particular LED is being produced only in limited quantities at present. I'm really hoping that changes sometime soon. Just to clarify, the regular (anodized aluminum) quarks do not come with the XP-G.
