Thought I had seen it somewhere else before. Like what has already been said... very expensive. If it wasn't (or they offered just the host) I would probably get one to convert to XML to make a good thrower or super bright multi XML light. Pity there are so few 18650 lights that hold 3x18650s like this does.
Like i said that is a real stupid price. The Jetbeam RRT-3 XM-L just costs 250 bucks shipped and it's with really good HA, 3 good Jetbeam 18650s, box, 2 years warranty, AR lens with 98% transmission (as i've tested with the RRT-2), SS bezel ring which is $$$, and most important of all the magnetic rotary ring UI with 5 lighting levels. And I think the RRT-3 looks quite a bit better.
And if you want me to guess, definitely there would be PWM present.
Loongsun/On The Road/Shadow are good quality stuff and i do use them and are happy with them, but still is in the realm of budget light level of finishing quality.
