I am thinking about adding one of these 600w Blackstars to my setup. I found a good deal on one from somebody but i don't know a couple things about them. Are they still the same as the 240 Blackstars? I got 2 of them and they are 3watt but this 600 watt is claiming to be 2watt leds. Also i tried to see if they sell the 600's in veg and flowering models. i could only find the flowering models available but this guy does not know which one he has. Just need some info whether these could be older units.... it has a good price of $450. Or would it be better to just add another 240w for the $275
