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

A new generation of Aqua Illumination Hydra lighting is here! The Hydra 32 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 32 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: 24" x 24"
  • Effective Depth: 24"
  • Recommended Mounting Height: 8-10"

Product Questions

How many of these would be needed for a 100 gal 48 inch tank.
Question by: Joel Norman on Jan 24, 2024, 11:23 PM
Hey there,
Thank you for reaching out to us. Two of these lights should work for you. The spread rate for each light is rated at Effective Spread: 24" x 24" Please let me know if you need anything further.
Answer by: Thomas Wofle (BRS Staff) on Jan 31, 2024, 11:25 AM
Hi, if I have two AI 26hd and two 32s is that enough light for a 125 72x18X22?
Question by: Devin on Jan 11, 2024, 7:32 PM
Hey there
Thank you for reaching out to us. That sounds right but really depends on what you plan on have in your tank. LPS and SPS softie's, fish only, and etc.. Please let me know if you need anything further.
Answer by: Thomas Wofle (BRS Staff) on Jan 31, 2024, 11:33 AM
My tank is a 31g Lagoon. The dimensions are 24.5”L x 18.5”W x 15.75”H. If I want to have SPS Corals how many of these lights would you recommend, or would you recommend a different light?
Question by: William Garard on Jun 6, 2023, 12:01 AM
This has an effective spread of 24" x 24" so you would only need one of these :)
Answer by: Ash (BRS Staff) on Jun 8, 2023, 5:08 PM
Suggested height is 8-10 inches. How high above the tank will it be with the flex arm mount.
Question by: RL on Nov 6, 2022, 4:56 PM
Thanks for the question! The flex arm mount allows this light to be mounted up to a maximum of approximately 16" from the top of the tank. Please let us know if we can help with anything else!

Would the Hydra 32s mount to Red Sea arms? I’m asking this because my Red Sea E-260 came with the same arms they offer now, but with Hydra 26s since the 90s weren’t available yet.

I really like the quality and function of the Red Sea arms and having them with a couple Hydra 32s on my new Reefer 350 would be great.
Question by: Rick on Sep 12, 2020, 10:40 AM
They will not mount to the Red Sea arms.

How many would you recommend for a 48x18x24
Question by: Brian Bosini on Sep 11, 2020, 3:10 PM
2 would be great. You would get even Par and coverage.
Answer by: Matt Lucero (BRS Staff) on Nov 5, 2021, 9:45 AM
Hi there. Can you please tell me what the measurement (inches) is between the two lights (middle of the fixture). I'm wondering if this would work for a 36 inch tank with a cross bracket. I won't have any coral on either end of the tank; 4-6 inches on each end of the tank.

Thank you.
Question by: Brian on Apr 15, 2020, 8:19 PM
Hi there,

It has a space of 2 11/16" between the lights. From our experience the cross brace will block out very little lighting.

Take care

Can I pair this light with my existing Hydra 26's?
Question by: HECTOR on Mar 9, 2020, 1:13 PM
Hi there,

Unfortunately not, the 26's are wifi controlled and the 32's are bluetooth. It would be possible to set them up together, they just have to be programmed separately.

What area do these cover looking at getting a new tank that is 24/24/20 decided between one of these or one single puck model
Question by: Matt on Feb 3, 2020, 3:23 PM
Hey there,

They cover a spread of ~20x20. I would go with 2 AI primes over the 32.

Take care

I'm not really seeing anything about depth? I'm new. Trying to find a Reef light for my 65g. 36"Lx18"Wx24"T and I am struggling.
Question by: Andrew on Feb 1, 2020, 2:04 PM
Hey there,

With most LEDs you will not see a depth given, they are all capable of increasing intensity to hit the depths of your average reef tank. 24" tall is no problem for these lights, however I would go with 2 instead of just one.

Take care

How many of these would you recommend over a 72x2x2 tank?
Question by: Curtis on Jan 31, 2020, 2:58 PM
Hey there,

I would not go with any less than 4, personally I would go with at least 5.

Take care
