Be confident in your purchase we're an Authorized AquaIllumination Dealer. How cool is that?!?!? You may be asking, "Is it possible to make the most popular aquarium lighting in the world any better?", and Aqua Illumination will tell you "The Prime 16HD, Hydra 32HD, and Hydra 64HD!" The new Hydras will give you MORE COLOR, MORE SPREAD, MORE POWER and MORE REFINEMENT without any sacrifice, keeping the along the lines of AI greatness. Better yet, the new Prime and Hydras are offered at the same price as their predecessor, giving you more bang for the buck! Design: The plastic construct of the new Prime and Hydra lineup benefits in two ways: better efficiency and better looks. The improvement to efficiency reduces the demands on active cooling for longer component life. Improvements to design a thinner fixture reduces their profile and presence over your aquarium. Resilient: Design improvements were made to the new Prime and Hydras to make them more water resistant, meaning that they are more resilient in moisture rich environments. Moonlight: A dedicated moonlight LED and channel has been added, so now you can control moonlight separately from the other channels allowing for simulation of the natural lunar color and intensity. Control: myAI app is free to download to control your lights simply and quickly with direct BLE connection. Optics and Output: Referring to PAR, the output, color mixing and spread has all been improved. With more LEDs, providing a full spectrum is targeted with TIR lenses that shape the ouput of the light while improving efficiency. As a result, there is more color pop, a wider spread, and higher average PAR. The combination of LED placement and lens geometry help blend the light cluster, reducing the color separation. The New Prime and Hydras share the same cluster of LEDs with the new optics. HD: The HD function of routing the power not being used by one channel into another is still a loved feature among the HD lineup - if it isn`t broke, don`t fix it, right? Mounting: Mounting hardware as previously available for Hydra and Prime fixtures will work with the new version lights. The exception is the Hydra Flex arm which will require a different light bracket due to the size difference in the new fixtures. The Flex arm bracket will change with he new fixtures. Older flex arms being used to mount the new lights will need a new light bracket. New Feature Breakdown: More LEDs More PAR More spread Improved optics Improved water resistance Thinner form factor Dedicated moonlight channel More channels for a wider spectrum Aqua Illumination Still Impressive Features: The best value Aquarium lighting on the market MyAI app control HD overdrive capability (route power to the spectrum you need) AI customer support The Prime 16HD can be mounted using AI`s existing Prime and HMS mounting accessories Numerous mounting options.
