I ordered on Amazon yesterday and it arrived this morning. Damn that was fast! First impressions are that it's a really nice little light. It's very lightweight, actually weighs less than the cardboard box that it came in. It's super bright for 100 watts and the spectrum is really nice to look at, to my eyes it's a slightly warm white. Obviously I haven't grown anything under it yet, but looks like it's going to do the job. I'm not ready to give up my 1K Hortilux just yet but I'm liking this little light so far.I just ordered the TS-600. It looked so cute I just couldn't resist. I'm not an LED guy but these look pretty nice, and are reasonably priced, and DC vouched for them. I'm building a really small grow box and was going to make something with some screw in bulbs but after reading this thread I figured for $100 I would give this thing a try.
