too much wait you could go with 2 of these they are way better and they each do 4.6' x 4.6' that is 9 x 9 at 480.00 each = 960.00

those are 5 watt diodes and would fill your tent with light.
NO! these are a waste of money, im just gonna go down the list..
1. Power Draw:
520-600w??? They cant tell you how much "their panel" is going to draw within a 50w range!? Ha I want to know within +-5
2. 240x 5w Emitters....(think about where they are are getting 5w... Volts x Amps= Watts... whether it be a LED driven at 3.5V's & 1500mA or any other combination...) when they are pointing out 5w, they are trying to "beef up" their panels, when there is no difference from what they are doing than what other shitty rebranded/chinese/or secondhand companies are doing with their product... They just think pointing out it is capable of emitting 5w's- that it MUST be good... but, those little emitters will not run the total 50-100,000 hrs driven at full capacity... which I bet is where they are getting their almighty "5w"
3. Viewing Angle: 90 and 120*.... if you look at the panel, there is no secondary lenses over the led's, so that means each individual nm'd led has a distinct Angle specific to it's "model/style/bin/brand" and I would bet they did not design/space out/and place those emitters to get the best spectral mixing/distribution/and coverage they could have with those LEDs' lenses.... I even wonder if they took into account the placement of the actual nm's of each LED for decent "symmetry" in the design and footprint..... (anyone have a picture?)
4. Uhm, probably my personal favorite Giveaway... Coverage numbers vs. dimensions..... Yea... wait, no seriously... check this out... (We all know coverage suggestions are overshot, THIS shit was funny to me...)
They give you the Coverage Suggestion... as 4'6"x4'6"... and Panel Dimensions as 460mmx460mm, Boom...! cant believe I never noticed this on other companies too... dead giveaway that they are obviously not stationed/produced/selling/mfg'ing where they are trying to push their products... simply a joke! They don't think people will see past this?
Now, I wont make another # for the exaggerated sugg. coverage of 5x5' from a 18x18" panel... then they go onto state "standard" after the suggestion, instead of a hanging height
I would seriously consider looking into something else if you are going to dip $1000 bucks into 2 lights....
Wait it out, I know 51's stock can be a PITA, but the last time that happened they were ridding themselves of stock for reason... (not trying to spam or get ppl's hopes up too soon, id be kicking myself in the face...) but another panel could be aroudn the corner, or maybe demand was just THAT through the roof... either way. It is something to look out for, they are a company on the rise that has talked about a smaller, more modular style, and a larger 4x4/1000w comp. style...either direction is promising... hell, the fact they are continuing to improve their products is promising....
For that large of a space, you are seriously investing your time/money/and efforts... you cut corners you are going to feel it later on. CLW is reputable in the fact that they "US," but they are just now updating their 5+ year old panels, that weren't ground breaking to begin with....
I am biased as fuck, but for good reason

No doubt, and until somebody to blow them out of the water- or even match- I am sticking to it.
