So, I spent approx. 4 months making this decision. I investigated and talked with numerous guys who purchased direct and had great experiences. I actually had a rep that I was almost ready to pull the trigger on prior to finding this new source. I chose the new source for a few reasons. First, the new Rep was much easier to understand and her response time was extremely quick, even with the time difference. Two, they were willing to negotiate because I wanted to purchase 30 units. The first Rep would give me quotes, but it always come out to about $185 per light regardless. The light would be cheaper, but the case would be a different price or the shipping seemed out of balance. I just didn't get a good vibe, but she came highly recommended.
After I found this resource, I had several conversations with my Rep, Bonnie. Again, she was easy to understand. She gave me several guys for referral and I talked with them. Out of the 150 lights that they had purchased, only one had issues and it was replaced without question with a new one in his hands within 3 days. It was also through those conversations that I was able to figure out the same factory was making these as for the original Rep. Go figure.
So, do your own homework. Don't take the word of anyone else and those that will talk the 'fear going direct doom-n-gloom'. Be comfortable in your purchase.
The manual lists battery life as ALL LED on at 3 - 3.5 hours, 6 - 8 hours in auto running mode and up to 20 hours with a single color on. I'm currently doing a battery test on a single unit. I have it going with a slow fade. 4 hours in and I've still got all solid, green power lights. The manual is very well done and easily to read (minus a few spelling mistakes).

I offered a bid of $1500 first, they countered at $1600, I offered the $1550 and they accepted. I placed the order on 1/18, they were assembled that week and delivered to me on the 26th.
** They also have a RGBWA-UV, if that interests you as well.
