Dang, just saw this thread today! Will definitely keep my eyes peeled for more of these! I am currently using phlizon LED's but am not that impressed with the product. The seem pretty cheaply made.
I definitely am going to buy a TSW2000 for my next round! Or perhaps win one
I'm very surprised with the quality of these Mars Hydro LEDs. I just got the SP 250 from Mars Hydro and just started a grow thread. The first thing that hit my mind when opening, was this thing is nice!!!
