I've never seen such a specific thread about such an unknown product! At first I assumed you were a salesman for that company trying to drum up interest.
What specifically did you like about the light? I don't know what type of lighting is best for black water diving, because I normally like to see stuff...I'm assuming you want a really wide beam? A video light might be the best bet.
I would probably recommend that you look into BigBlue video lights or technical lights, they have some with that multiple LED type design that might be similar, and while BigBlue is clearly importing Chinese made lights, they are a well established, well known brand, that I would have no problem diving with.
You might also want to look at the older HID focusable lights, that would have the benefit that you could get a wide beam for cooper diving, then a narrow beam for clear water diving. But they aren't going to have quite as even of a wide beam as a video light.
If the wide angle isn't super important, you could look into something like Dive Rite CX1 with a diffuser. Will be less lumens and possibly less burn time than one of those bigger lights, but it will be cheaper. I could use a CX1 as a primary light in a pinch, and that gets you a diffuse light with diffuser, and a narrow beam without, so it's more flexible. If you have the cash, then I would recommend something like the LX20 or even HP50, but none of those will have as wide a beam as a video light.
