Orphek OR3 attachment to hydra 26s over REEFER425

[TheGerm]

Hey Ya'll,

Looking to see what people think about mounting two Orpheks (OR3 35") on either side of the hydra 26's. I am not sure how much the light bars weigh, nor am i sure of how much the stock AI/RedSea mounts can hold.

I have no issues either making or 3d printing a mount for them, just trying to get a consensus from the community if this is possible.

(i have not ordered the Orpheks yet, but this would be a project if i do)

how many total ai hydra mounts on the tank? I think each hydra 26 weighs 2.2 lbs, and the orphek bars weight 4.4 lbs each @ 35".

2 mounts, 2 hydras, 2 OR3s: 200% weight increase
3 mounts, 3 hydras, 2 OR3s: 133% weight increase
4 mounts, 4 hydras, 2 OR3s: 100% weight increase

I think if you have 3 or four mounts it will be good, assuming the more distally mounted or3 bar is placed really close to the hydras. Two mounts is kind of sketchy. It will probly hold, but any bump of those lights and you're in trouble.

They’re decent mounts and should hold firmly

There are currently 2 hydra 26s mounted with the default "swing" arm (they and swing up to allow you "access the tank better"). Like these: https://www.saltwateraquarium.com/r...ounting-arm-for-24-27-wide-aquariums-red-sea/

They seem very sturdy, but at the same time i did not know 2 OR3s would be ~8-9lbs. That maybe an issue... hmm, maybe i could make a new/modify the current mounts to make them stronger.

idk... just got my PAR meter in and will be doing some testing. If i dont have enough (320+) i will need to add some light, but id like to keep it "stock" looking or as slim as possible.

The stock Red Sea AI Hydra 26 mounts are pretty beefy aluminum.

Should be fine

I ordered two OR3s. Each light bar itself weights 3lbs and the cabled power supply is another pound, but that would not be above the tank. In total, the amount of weight being added to 2 light arms is 6lbs (not 8-9 like originally thought).

I am going to do some manual testing and positioning, then work on a bracket. I will try to keep this updated with the result.

Purchased the lights, which made me create the mounts. With a little 3D printing and some aluminum strips, i created a support brace and mounting points for 2 OR3s.

Setup is solid and i am liking the look. Not too shabby, but wish i could hide the wires more, but i will get used to it .
