I bought mine at http://www.batterystation.com/lx3.htm Light is long, 7 and 5/8 long. My tint is slightly green. Beam has an off center, square shape with a circular beam shape off center inside the square.
Shipping was fast from Battery Station
First, he is asking about the Gerber TX 3.0 not the LX 3.0. This is a new model that was shown at the SHOT Show. From the Pocketlights.com Blog, "The Gerber TX 3.0 is the tactical version of the Gerber of LX 3.0. It has a black anodized finish, an anti-roll bezel and tactical push button switch with a lock-off mode to prevent the light from accidentally turning on. The TX 3.0 comes with black nylon sheath and retails for $60.00."
Second, I don't think it is available quite yet; I haven't seen it on any sites.
