As far as I gathered and the info they had on the website
http://www.solaroasis.com/grow_overview.htm
they look like you can do the full capoodle and although they are expensive compared to the normal MH/HPS lights, the gains may outweigh the costs. I was comnsidering just using a 400Watt HPS instead of the more meaty 1000Watt I have and then supplementing with those to boost up and beyond what I was going to supply my plants and with a big reduction in heat, electricity and bulb replacement problems. If I had some testimonials I may even axe the mixed optiuon and go full LED!
