I say it all the time...apache's website blows. I want to know all those kinda of things so I call and ask. He does the readings with a licore par meter in a huge non-reflective room. I use the growers house 1000w test to compare things too all the time. They also have a bunch of "top" led's tested to. They use a par meter and show readings all over the foot print at different height, not just peak. It's a really good way to see how the light is performing all over. They are all in my thread post #69 and also the at660 test like that I did myself is in the tread too, post #86.
I like apache obviously, specially now that they are fill the bigger growers needs. But I think everyone also knows that a51 is my #2 pick. They make some good lights at a great price and his website is like looking in my own mind. It's just isn't different really from the AT120's I already have had for a while. And I needed something bigger.
I don't really know where I am going with this other than, Apache, A51... fuck ya America!
But seriously when you look for the best quality lights available on the market you basically come down to Apache and A51. umol/w and quality components throughout they blow the rest away IMO.
I would like to see a normal person using a illumitex. The light I saw at the max yield show wasn't coming out till october, but it did 800+umols at 12" everywhere on a 4x4, I tested it. It is what rocky mountain high tested in that hightimes video.
Edit:
Not the official test but better than most.
