Same issue. Problem is those pucks in a line cannot get to the edges on a 24” wide tank.Thanks Boom. I am not sure why the 3 xr15's keeps coming up, it's 4 that I would be using. What's your thoughts on the 4?

That's the issue I worry about with any of the leds. The orphek is only 9" wide.Same issue. Problem is those pucks in a line cannot get to the edges on a 24” wide tank.
I don’t recall exactly how coverage was when I had the V4. I think I had coverage issues with just the one V4 unit. Two I imagine would cover fine? (I hope)That's the issue I worry about with any of the leds. The orphek is only 9" wide.
You said "had" the V4. Why do you no longer have it? Two would be the same as the radions, in a straight line across the middle of the tank.I don’t recall exactly how coverage was when I had the V4. I think I had coverage issues with just the one V4 unit. Two I imagine would cover fine? (I hope)
People forget frag tanks are not reef tanks. When you’re trying to cover a 48”x24” x12” space packed with acros, it’s not the same as a 48”x24”x 18”+ reef tank with live rock, scaping, etc. Shallow tanks where corals are 6” below the surface do not get the benefit of “reflecting” light like you do in a regular tank.
Correct. I ended up with all halide or T5 after testing pretty much every LED there is. I don’t want to spend $2500 per tank I want to light when I can spend $700 on halide. And the wattage usage of radions or orphek or sbreef we’re not much lower than 500w of halide. A single xr30 running 100% uses around 140w.You said "had" the V4. Why do you no longer have it?

There might be some reflection as I grow them on tiles. How much that reflects I don't know.
I agree with what you are saying. I wish I could go t5's again but the heat is just too much.Correct. I ended up with all halide or T5 after testing pretty much every LED there is.

Is it the shadowing effect comparable to pure T5s?Hi I have been using the Orphek Atlantik v4 for nearly a year now and I have to say they grow acropora and sps like weeds(we all know lighting is only one element of reef keeping)
But I’m more than pleased with the kind of light it provides
I’m using 4 units
Just wonder from the heat standpoint, is it Orphek when all channels are 100% is much cooler than Halide?Correct. I ended up with all halide or T5 after testing pretty much every LED there is.

Thanks for the valuable feedback, u have an impressive tank there mate.Ken,
There the best leds have ever been at producing a blanket of light but similar to t5 you are aiming to cover the whole of the waters surface with units to provide full coverage and minimal shading
Heat wise they run way cooler than halide
Currently running at around 40deg directly at the heat sink (which is the full foot print of the unit)
Cooled by 4 large fans per unit these are virtually silent even now
It’s 32deg outside and these are not making a sound
The old radion these replaced used to scream at 100% intensity!!!
Cool, Thanks again mate.Cheers ken!!
Well my nutrients are very low at the moment I have just been on holiday and the tank was on very minimal feeding.
so a few weeks prior to going away I brought my intensity down to around 600 watts at peak
But I essentially have just over 1000 watts of power to use if needed
Colour blending is perfect when mounted at 17 inches above water line.
But I have mine lower because my tank is Euro braced
The construction of the lamp is kind of a laminated design of various layers of acrylic
The leds are individually lensed and this reduces glare from the sides of the lamps
I will say they are heavy units!!!
At 100% with as many orphek as I’d need I would say it’s only a tad cooler. 1 watt of lighting is 1 watt of heat regardless of the source.Just wonder from the heat standpoint, is it Orphek when all channels are 100% is much cooler than Halide?

There are a lot of great reasons to choose either, but the word from a LFS employee about some generic study probably not one of them. What a retail shop does, or a research institution (allegedly?) is using when not directly testing a light is really of no consequence. If the dude/gal did give you some specifics, I would LOVE to read about some coral spawning research - the only stuff that I know about is in Hawaii and Fiji and they use natural sun and 1000w MH.
