Soon i will be upgrading to 4 x126 leds per table 3.5x3.5 and comparing them to 600 watt.
If everything goes well, looks like a $25k LED upgrade for me.
( would save me about 3000 watts pr hr a day)
Can't wait to see the test! When you do decide it's time to upgrade, let me know and we'll work out a price for you since it seems like you want quite a few panels
