On my quest for the perfect light (for me) and its led me to the orphek amazonas 80 or 320. Contacted Oprhek and they recomended the 80 because the 320 is not dimmable nor programable from the sounds of it but then the 960 is indeed back to dimmable and programable. Why they would no make the middle ground light controllable is beyond me. Has anybody had any first hand experience with any of these? How is the PAR, spread, shimmer, side glare. So far I have toyed with radion gen 4 and they blind me to all heaven to the point where I hate to even have them on. Kessil a500 is my fav so far especially with reflectors. Im really digging the light being funneled down into the tank rather than my eyes.
