Ai Hydra 26 HD vs Ecotech Radion XR15W G4 PRO

Really struggling to decide which LED fixture to get for my new 18" cube tank.

Both are very similar in price, however the 26 has two pucks whereas the Radion only has one. As I'd only be buying one fixture I'm worried that the one Radion might cause some shadowing effects whereas the Hydra would be less noticeable.

I plan on keeping a mixed tank with a hand full of SPS but nothing too serious, an anemone and clam are also on the wish-list but I think either light would support my needs.

The tank is also in my room so noise is a big factor when it comes to choosing. Any advice anyone can offer is greatly appreciated. Thanks!!

Out of those 2 options I would choose the Hydra.
You'll get better spread like you say since it has dual pucks. And you wont need to buy anything else to program/control it. The Radion you would beed to plug into your PC to program unless you buy a reef link.

I have the AI Hydra 26 and they do an awesome job on both SPS and LPS. Very easy to use and program.

Yeah I am leaning more towards the Hydra. They're slightly cheaper and I don't really want to spend the extra £100 on a reef link although I will be getting an MP10, I can't see the advantage of linking my pumps and lights.

Thanks for your advice

Looking at longevity I have a friend who still uses his G1, I have another friend who has replaced his pucks on his AI's a few times. I do have to say his last purchase of AI's have lasted longer than the earlier generations. He uses 6 on a 5' x 30" x 27" tall tank. On another note I just spoke with a member of our local reef club who was picking up the PAR meter and he loves his XR15 G4 Pro.

While I would be inclined to go with the Hydra 26, might wanna give that Radion in conjunction with a "diffuser" lense cover a second consideration. The PAR drop off was only about 15-20% at 100% settings but The PAR through out the tank was much more evenly spread and higher over all with less shadowing and hot spots.

I was a heart beat away from going with Hydra 26's but now I am considering the Radions really hard again...Man sometimes this hobby really sucks - so many options!

Ahhhh!! this thread was meant to make it easier to decide haha. I had forgotten about the diffuser, considering the radions again now. Does anyone know of the xr15's being noisy/loud?

To add a little more to the mix, I have found a great deal with a second hand Kessil A360WE with mount and controller for the same as a Hydra 26 - any thoughts?

I run 2x26s on a 48"x26" tank, the coverage is amazing.

Aah you found the rabbit hole It can get overwhelming with all of the choices. I have a Ai Prime HD and a Kessil 160 I like the AI HD color temperament better than the Kessil. The AB+ is really nice.

I think I’m gojng to go with the Kessil A360, I’ve found one with a goose neck and controller all for £250 where as the Hydra + mount was just under £400 and the xr15’s were around £430 all in. Thanks for everyone’s input really appreciate it! May start a build thread if things go well!!
