Ah so
@Dr.Nick Riviera , I was right to take what you said the way I interpreted it.
End of the day, yes they are advertisers who sell lights, but regardless of if YOU trust them or not they have a good reputation as opposed to the lights in the title of the thread. Plus it was mainly the users of these lights who recommended them, not the actual designers or sellers who actually just pointed out what the OP should be looking for in an LED. Stephen and cobkits did not spiel out a sales pitch or suggest the OP bought from them.
I have seen both recommend lighting from other sellers if geographical location or their own systems didn't suit the buyers needs.
You don't have to look very hard to find great examples of grows using any of this LED tech.
