I would not go anywhere near them.
I bought 4 lights, two were faulty, and after sales support is non-existent unless you want to repair things yourself, and despite the lights still being under warranty.
Yes the owner and support staff are very responsive on email, but it took several hours of back and forth email correspondence to diagnose the problems (having to open the lights and run several tests on various components myself).
I was then told the only way to repair them was for them to send me the replacement components and do it myself (including soldering). I went ahead with this only to have one of the lights fail again only a few weeks later...not what you expect when spending $3,400 on a “high end” product.
There is no replacement or refund policy so if a light is faulty you are stuck with it and need to repair it yourself. If you are a DIY person and have a lot of time on your hands then it may be fine.
