I had also talked myself into it, after having read and participated in many of the discussions. I even had one on order.

Then I got to doing some real research on my own, at the 2 LED manufacturers sites. That's when I discovered this basic fact: except for incandenscent lighting, all lighting has pretty much the same efficiency/inefficiency.

On top of this, I've not seen a SINGLE decent SPS testimonial, with before and after photos, showing that growth and color are competitive. Now, understand that it's been a couple of months since I last checked. Is this STILL the case?

Other than that, I'd love to see what they look like. Let me know if you buy one.
