More Color, More Spread, More Power, and More Refined

A new generation of Aqua Illumination Hydra lighting is here! The Hydra 64 HD has been redesigned making the reef lights more efficient with better aesthetics. The Hydra Lights have been a staple in the reefing community for years and the new Hydra 64 HD Lights take the same great features and benefits while using more efficient hardware that ultimately gives better light and spread throughout your aquarium. 

  • Easy Control with the MyAI App
  • More LEDs
  • More PAR
  • More Spread
  • Improved Optic Design
  • Improved Water Resistance
  • Thinner Form Factor
  • Multiple Mounting Options
  • Dedicated Moonlight Channel
  • Wider Spectrum (more channels)



Redesigning the plastics in the Prime and Hydra lineup has resulted in two major benefits: better efficiency and better aesthetics. Efficiency improvements reduce the demands on active cooling for longer component life. Improvements to design thin the fixtures and reduce their profile and presence over your aquarium.



Water-resistance is a major benefit in aquarium lighting - and while the new Prime and Hydras are not waterproof, design improvements make them more capable of facing the moisture-rich adventures of reef keeping.



A dedicated moonlight LED and channel has been added in the new Prime HD, Prime FW, Hydra 32HD and Hydra 64HD modules. This allows for independent moonlighting designed to simulate the natural lunar color and intensity.



Control on the lights will use the existing myAI® app which is free, simple and very quick to a program offering onsite direct BLE connection through your smart device. Additional control options may become available for the new generation Prime and Hydras over time.

Compatible with MXM

Neptune Systems, EcoTech Marine, and AquaIllumination have joined forces to bring MXM to life. Now all your favorite EcoTech and AI pumps and lights can be under the wireless control of Apex & Apex Fusion—the user-friendly, yet powerful, interface you already know and love. No more switching between multiple apps.


Optics and Output

Output in terms of PAR, color mixing and spread are all improved with the new fixtures. The incorporation of more LEDs results in a more targeted full-spectrum, TIR lenses shape the light’s output and improve its efficiency. The result is more color POP as well as a slightly wider output area and higher average PAR. A combination LED placement and lens geometry blend the light from the clusters so that color separation is further reduced.



  • Effective Spread: 30" x 30"
  • Effective Depth: 24"
  • Recommended Mounting Height: 8-10"


The Hydra 64HD delivers more output with a higher average PAR than any other AI Module.

HD AI’s popular HD functionality, through which a user can route power not in use by one color channel into another color channel is a much-loved feature on the previous generation HD fixtures. As the new product names imply (Prime 16HD, Hydra 32HD, and 64HD) all the new HD lights retain this exciting feature.

Product Questions

I have a 32L x 24W x 24H, 80 gallon rimless tank.
From the specs, It looks like I'd only need ONE these for my mixed reef tank.
Can you please confirm this?
Question by: Shawn D on Jan 17, 2024, 8:13 PM
Hey there,
Thank you for reaching out to us. You got that right. Since the effective spread rate for that light is 30 "x 30" your all set. Please let me know if you need anything further.

My tank has 3 AI Vega color LED lights on it, will a hydra and controller work with the Vegas also so they can all link together
Question by: Ron Wolfe on Feb 4, 2020, 3:27 PM
Hey there,

The AI vega controller will not work on the new AI 64. They are bluetooth controlled only.

Take care

I have Aqua Illumination hydra 26 lights, if I purchased a hydra 64 can i program them all together.
Question by: Michael Mossey on Feb 3, 2020, 2:03 PM
Hey there,

Unfortunately they are not able to be paired together. They connect wirelessly through different means, one is bluetooth and the other is wifi only.

Hi can you send me the links for the flex arm and new light bracket for the AI hydra 64HD I have a rimmed tank but it looks like it will be wide enough the rim is 1 1/4” thick
Question by: Michelle Mitchell on Feb 1, 2020, 7:11 PM
Hey there!

Will one Hydra 64 be sufficient to cover a 36" peninsula(40 breeder) SPS dominant tank?
Question by: Zach on Oct 22, 2019, 12:14 PM
Hey there!

Unfortunately that light has a spread of 32" only. I would recommend two smaller lights like the Hydra 32.

Take care
