Lumepower ballast? Price was a blowaway..

I saw that Lumepower banner on a bunch of the MMJ sites. I had heard of the brand but never used them. I bought 20 of them, got them, installed them and they have been working great for a month now. I was suspect of the price and called the company and apparently they get them direct and don't have to add on the distributor and store margins. If your looking to get a good ballast at a fricking ridiculous price, you should check them out at lumepower.com

Does anyone have any experience with these? Good growing....
