Well, our connection seems to have gone dead. Last time I got this much silence from a dive light manufacturer was when I tried to contact Magicshine for service.
I can provide some feedback based just on the information provided. This seems to be a start-up venture by a company manufacturing LED lights for surface use. These lights don't seem to have much presence on the US market but do have some mixed reviews and testing from the LED light community. I suspect their only UW lights are a few prototypes and doubt if there is any ongoing production. (The illumination for the 8 minute video looked like it was provide by some other light.) The two dive lights seem to offer little in the way of competitive features. I see fairly low power, short battery life, and flooding. I expect reliability will be worse than competitors' due to inevitable early production problems and using the button control which will provide another opportunity for leakage. I'm sure they will use the same inferior "made in china" o-rings that are a problem with so many dive lights from there.
If you think this light might be interesting, take a look at the Trustfire alternative. Of course you will need to replace the crappy original o-rings with some quality ones and then correct any other manufacturing defects; but in the end you should have a very inexpensive ($30) and fairly useful LED dive light.
