I want the 150ext and I would go all Quanta's (like I'm running now). Luca will be coming out with his panel light in a couple months. 2 channels, 0-10v dimming and will have his own controller/timer. The panel will be as high as two iPhones stacked on top of each other, so pretty thin, 210w and the spectrum will be as close to the Atlas and Meso Blue combined. You just control the intensity of each channel to give you the preferred spectrum (more white or more blue).
