AI Hydra 26

Experience Level: Intermediate

Comments: Excellent build quality. Compact but powerful. Two units flood my 36" long and 24" deep tank with plenty of light, (running at 60%, 10" above water surface). New controller allows great flexibility and precise tuning of light color, intensity and scheduling. 5th star held back, for lack of any instructions with controller. Although the programming is fairly intuitive, I had to look around online for instructions to connect the wireless controller to the light fixtures. End results were well worth the effort.

Comments: I don't usually rate something as "Perfect" but these lights truly hit all the marks. They are very well engineered and the output is blinding! I purchased 4 of them for a mixed coral reef tank (LPS & SPS) with 60"Lx27"Wx22"Tall dimensions so I would have the coverage and blending I wanted from the light. It was the perfect amount with the limited distance above the water line I had to work with. I ended up suspending them 8" AWL oriented length wise front to back. Even then it gave me only 3" of clearance to the canopy which from what I could find online is the minimum recommended for heat management. For me it was a choice between the Radion 30 G3 pro's and these. The output of these is lower than the Radion's but with 4 of them in the tank I have it is still more light output than I need. So the coverage and blending I get with 4 of these vs. 2 of the Radion's at a slightly higher price was a better look and function. I'm very pleased with the purchase, hope this review helps.

Comments: The light is great so far but the instructions and paperwork that came with the product are lacking. It was not clear and took some time with trial and error to program. Also it makes no sense that this is called wireless because you have to have the remote control plugged in. The control does not even have batteries! Wireless implies wifi or at least info red remote, and it's neither

Comments: I required more reach in the corners for my SPS dominated Reef Tank and already having the Hydra52's programmed and running for about 2 yrs. now, the addition of the Hydra26 was a perfect match with the 6" Extension. I installed and configured them in minutes. Great PAR and reach. Well built as always and still Made in the USA, which is very important to me.

Great Upgrade from Sol Blue

Experience Level: Intermediate

Comments: I love these lights. Coming from 3 channels to 7 channels makes all the difference. I also like the 80 degree optics and the frosted lens covers. The spread is much better than the 40/70 optics on the Sol Blues, with no hot spots. I have two on a 46 gallon bowfront perpendicular to the front, about 7" above the water line. AI has changed the legs for the mounting rails, which set the lights about 4" higher than the original legs which had the units only about 3 inches from the water. I'm sure a lot of users were complaining about this. Definitely recommend these lights (and the new legs), especially for anyone putting them in a canopy. With these lights I have control over the entire spectrum. Good job AI!

Comments: i guess the only thing that was not "cool" with the product was the fact of no instructions being sent with the product. A few online search's latter and I am all set! So far so good, just trying to see what light looks the best for me.

Comments: This lighting system is perfect. The wireless controller accessory is a must. (I never write product reviews, but I had to for this one). I have a 29 gallon cube aquarium, and it's more than enough. A bigger aquarium may need the FiftyTwo. It is good to experiment with the colors. I turn the white down to around 60%, and the blues up to around 90%. I leave the other colors around 70-80%. It looks amazing. My previous lighting system was the Kessil Tuna Blue A350. (They are the exact same price). The Hydra Twenty Six is superior, I could not go back. The color of the light just looks way more pleasing, and there are limitless options to customize it. As far as I have read, corals grow very well under multi-color LED systems like this, although I haven't had enough time with it to report growth. The corals (and everything in the tank) certainly look better under these lights, which is important too. The saving grace of the Kessil is the single point source, which gives very strong, crisp refraction lines if you have surface agitation. It gives it a very ocean-looking effect, which is super cool. You do get decent lines with the hydra twenty six, but not the sharp, crisp ones that the Kessil can deliver. I have also had experience with the older hydra from AI. The TwentySix and FiftyTwo are enormously better, I wouldn't recommend the older version. Although the functions are by far the most important part, I would also add that the build quality of the hydra is impressive. My Kessil came apart within a week and I had to solder it back together. Most people probably don't have this experience, of course. But if you dropped the Kessil, it would basically shatter. I'd be more worried about my floor than my light if I dropped the hydra. It's a brick.

Comments: Awesome Light and works fantastic with the Director unit. Covers my Nano cube perfectly and will also be powerful enough when I upgrade to my 100g. I'll just be adding a 2nd unit for coverage at that point.
