I liked the spectra lights, but mostly because of the look. I felt i could add some lumens with a homemade system with full size lumenmax reflectors and some LEDs, and once i decided to box in my setup with cabinet looks didn't matter. One of the reasons i boxed in the system was that with 400 watt mh lights i felt like we were going blind looking at the tank. Much easier to just relax with a drink and observe now that i've abandoned the open top. One other advantage is i'm back to VHO actinics, and i really feel they add something that the T5s supplements didn't quite do.
I copied the light fixture design, with some changes, from someone here at RC. I think i have a few comments earlier regarding that, but when i get a chance I'll try and do a little video clip of it moving up and down. Works well.
