I've never seen a company include which companies they went through for their lighting (Bridgelux, Epistar, EpiLED) within the page of their advertised product. A first in my book.
760 Actual Wattage for ~$1,400 seems a bit high and expensive, especially since it's nearly the year 2015 and were talking about Bridgelux, Epistar, EpiLED lighting. I understand that there are people out there (you may be one of them) that have a few extra grand laying around and that love trying out new LED light fixtures such as Truth Lighting's M16.
It's boxing design isn't new. The lighting design may be positioned differently though.
My guess is that they went through the (Chinese) makers who offer the cheap replicas that you see on alibaba.com and gave it a facelift. Do I think it's worth ~$1400? Hell no. Why do I not think it's a fair deal? Well because I could make one @760W for no more than $700, which means they most likely made it for ~$350 and are asking for a 400% markup. It may not be as fancy looking or have as many individual LEDs but my product would be designed better or at least specced out to a higher degree.
