See my earlier posts in this section. I love, love, love my Illumina. It was a bit complicated initially, but WOW, now. It took me a few days to connect with their very helpful North America distributor. Email me and I will send you the operators manual that for some strange reason does not come with the light, and the secret tele for the distributor that will answer any questions that the retailers cannot answer.
This video helped me choose it. BTW, I have a 24 inch deep tank and bought the SR200. And I have been unable to control it with my Mac and had to buy a used PC laptop.
