Yeah, I just finished reading it and thinking about how far the industry has come in the last couple of years. Dec '13 - Dec '15 is only two, last I counted. Maybe you got the new math?
I remember reading some of LEDgirl's posts, I've seen the Illumitex lights up close, saw the Black Dog led come and go, saw the Mars Hydro thread here on RIU. I had and ran an Xtreme LED 200, I was very disappointed.
Now for the good news; I've seen scads of grows with CXB3590 chips and they all look fantastic.
I'm convinced enough to throw down some very serious coin for a large LED array to go head to head vs high wattage HID setups. I should get my custom built modules this weekend, and the new year will see some very interesting comparisons.
