I have the TridenX but it is going back to Performance unopened. I am returning it because I got a good deal on the 600L (Rob upgraded both my 200L and the 140L to li ion so I can share batteries among them). PerformanceBike do have the TridenX on stock even their website says otherwise. I was surprised when I call them last Monday to cancel an order placed Saturday but find out the light was shipped.
