ATI Aquaristik is no stranger to aquarium illumination. For many years, their Powermodule T5HO fixtures have topped the wishlists of many a hobbyist. But over the last few years, T5HO lighting has waned in popularity, giving way to LEDs. ATI seemed to have reisted the trend, as they slowly adopted LEDs into their lineup and only initially as supplemental lighting in their Powermodule hybrids. But, the times seem to be a changin’ and it appears that ATI is finally coming fully on board with LED technology as their latest light fixture sports nothing but tiny little emitter goodness. The ATI Sirius X LED fixtures sport an array of LED clusters, with each pulling about 75watts. The clusters are composed of 13 LEDs each, with the embedded colors being six Cree XPE Blue, two Luxeon M Royal Blue 450nm, two Luxeon M Cool White, two Cree XPE Red 620nm, and one Semileds Violet 420nm. This grouping of LEDs is further broken down into four independently controllable color channels, and to further play to our contol freak needs, the individual clusters themselves are independently programmable from others in the fixture MORE: ATI Finally Goes Full Fledged LED with New Sirius X Fixture
