How can you not see that these guys are trying to help you? I'm new to LED and almost bought those same lights you have 6 months ago but my gut told me to research a little more because I wanted the best in what LED had to offer as far as efficiency, lower heat, safety and most of all, end results.
I invested a lot of time reading and reading especially this very forum. I still learn something new everyday.
The guys above have shown their results time and time again and I've seen the results of the mars as well. It's like night and day. A little research will show you that with your own eyes, not just word of mouth.
Everybody suggesting better options have went through the trial and error with LED to find the best, in turn helping the next guy avoid the pitfalls, especially Supra who's an asset to this community who goes out of his way to spread knowledge and help growers for no profit whatsoever!
You have your lights, do your thing. If you like the end results and your fine with your power bill then rock on. But if you feel yourself wanting more then the info is right before you. You ditched the hps, it'll click soon enough.
