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!

What`s New and Cool:


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.


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.


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.


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.


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 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

Best light for your money

Pros: Lesser cost = more goodies you might underestimate the benefits of

Cons: Could have a few more presets built in

This is hands down the best light for your money. Extremely adjustable for any spectrum you wish to achieve. The HD option is a big plus. If you haven’t had aqua illumination over one of your tanks you don’t know what your missing. It is in my opinion the best par per dollar you can get.... with the price difference of some of the other lights you can by more goodies for your aquarium and have the same or better results depending on your settings

Worked OKAY for 9 months

Pros: Good light when it works, Quiet, Not too Hot (not much to compare to)

Cons: Automatic Schedule needs Reset every couple months, Breaks. HORRIBLE RMA, lackluster Customer Service. (Friendly but not as expedient or caring about the health of your tank as, say, Kessil)

Worked "great" for 9 months, only real issue was that the Wi-Fi control would keep resetting every few months and would have to re-login and re-establish lighting schedule, this was a major inconvenience, but other then that, the lights worked well, were quiet, provided a good spectrum of light.

Fast forward 9 months and the light stopped working, I contacted Aqua Illumination, provided by receipt, everything, they gave me an RMA, had ME pay for shipping to send it out, a week later I get my same busted broken light back with a letter saying "No repair needed". I plug it in, still broken! Now having to deal with back and forth of having to get this taken care of.

Compare that with my Kessil experience last year, in which a 360 I had broke (after about 12 months of use, these LED's just don't last as long as the marketing claims), I contacted Kessil, they sent me a BRAND NEW LIGHT, no Questions asked! The only stipulation was that I send back in my old light, on my own time, within 90 or so days, or they would charge me for the new one.

I'm never buying another Aqua Illumination product and based on my RMA experience I would highly implore no one else ever do, either. It's not worth the hassle of when they eventually break. I'm sticking with Kessil for NOW ON, just based on the RMA factor alone and the excellent customer service and looking out for the health of my corals. With Kessil, I was able to use my supplemental light to keep my corals alive for the 2-3 days until the new light came in the mail, and was able to return my old one at my leisure. With Aqua Illumination, I had to scramble to find a decent light that wasn't too expensive to use while I waited the 1-2 weeks for my product to reach them, them to work on it, then ship it back. SO NOT WORTH IT!

Great Light!

Pros: Great lights with easy setup

Cons: Expensive brackets / Mounting options

I've had both the 26 and 32 versions of the Hydra and both never seem to amaze me with the light spectrum provided and simple initial setup!

Love these lights!

Pros: Look good! Good growth, quiet fans.

Cons: Sometimes it's hard to get them to connect to my phone but it always works in the end.

I'm running 2 of these with 2 ai prime 16hds on my 4x2 mixed reef tank and have been very happy. There are so many schedules you can download for them if you join the Facebook group for ai and I've been very successful with them. My tank is only 3 months old and the growth has been amazing. Very happy!

next level reef lighting

Pros: price and the ability to fully customize light schedule

Cons: Need more Instructions on how to use the app

Compact yet powerful light that is fully customizable to fit your reef lighting needs. Value packed with lots of features.
The app is great but takes some getting use to how fully operate all its features
