Yes the Gavitas are meant for WH and GH applications. And my thought process was the same as Heady's couldn't really see the sense in buying the flex. Im always about more.. always have been Yes the Flex set at 825 is supposed to rival a conventional 1K. I know you can save money and time in many ways. But for me to be able to hang the light snip in the controller and be done.
Valid points Jhhnn. Ive heard good things...It would only make sense being able to run these lights closer to the canoy in a short ceiling or tent situation. What type of 1K system were you running before? What are you comparing the 630 CDM too? And when you say Duel Stage cooling you mean Air cooled hoods and Hvac system as well? Passive Air Exchange? Not sure I follow...
Had to do an edit..Wow i was just reading about the DL systems and controller. While more expnsive option over Gavitas. The controller has allot of options. Really cool. I would love to see the performance over HID with the 630watt for sure. You have peaked my interest. I was at a store the other day and saw one hanging and did not pay any attention.
I was running a plantmax dual arc lamp on a 1000w mag ballast.
Two stage cooling in discussed in the ventilation 101 thread. There's a fan that pushes unfiltered outside air through an enclosed hood and another smaller fan w/ filter to move air through the enclosure. A lot of the heat from the lamp never gets into the enclosure from the hood & filters last longer because there's a lot less air going through them. In my situation, a house with a big evaporative cooler & no A/C, I had trouble keeping good temps in the summer w/ the 1000w system but none using the CDM's. I turned down the fan for the light for less noise but had to keep the fan venting the enclosure at the same speed because the radiant energy entering the enclosure is about the same. The CDM's produce a lot less wasted energy as infrared & conductive heat from the lamp.
I can have the tops within 12" of the glass w/ no problems w/ the 630 setup. I haven't let them get closer. 18" or so works great.
