Radions or Orphek Atlantik's?

[Ken Lee]

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.

Base on your feedback previously, correct me if i am wrong that what u are saying is that 500W Halide with good huge reflector is equivalent to 2 unit of V4 coverage & punch?Or u referring that V4 = 250W halide. If yes then i am agree with that equivalent wattage will bring similar heat generation.

I have an Orphek V3+(isnt as good as the V4, but close) and ran G4’s on my previous sps tank.

Orphek is a better light. Coverage is better and the spectrum is wider. Im back to Halide as nothing in the Led world comes close to it in coloration, but that a discussion for another thread.

If I were to run led only, a V4 would be it. Many top growers use G4’s because of sponsorship, but Im positive if they ran V4’s they would be surprised.

Orphek are some serious lights

I heard that with V4, we don't need yellow filter when taking photos with our phone, assuming all channels are set 100%?

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

Amazing results!
I dont wanna mess up this threat but would you mind sharing your program via PM?
Got 4 Atlantik for SPS dominant tank
Thanks

If someone wants to donate a V4 to me I’m happy to test it side by side with a halide to compare long term growth and color.

I thought you had it already?

I had one to test over a tank for about two weeks. It was a friend’s who let me use it until his new tank was set up. I got to test PAR and Spread but not color and growth. Looking at my list I’ve tested the following for color/growth: Radion G4 pro, SBreef, Kessil, AI, Black Box (mars aqua)

Oh I guess I assumed you tested them thoroughly and came to the conclusion that they weren't very viable on the low boy. Partly because what you said is why I went a different route.

They aren’t. The spread didn’t get to the edges. The outer 4” of each long edge was getting under 100 PAR. So on a 24” wide lowboy you’re losing about 8” of that. That’s a lot of real estate!!

So if I run one T5 on each side of the Orphek, it sounds like I'll be set for par on a 24" wide tank.

Maybe. One T5 might bring that up only about another 50-75 PAR, depending on the reflectors. Two on each side would absolutely do it though.

Seems like BRS is the only place you can buy orphek?

 

[bubbaque]

Brs video shows par of 200-250 on a 120 gallon on the outside edge with one Orphek. A 120 is the same perameter of the low boy. I wonder why the par is so different than what you were getting. I was going to run two of them.

Because they aren’t taking PAR readings at 3”-4” below the surface at the edge where your coral sit when using a 10” tall low boy. I also had to turn them down a bit from what BRS had as 600+ PAR of LED in the middle is going to fry some acros.

What about attaching an OR strip light?

 

[bubbaque]

This is a screen shot from the video. This is the par at 6" deep (low boy is 8") and par at 12" using their custom light setting. It seems as you go deeper the outside edge gets more par and the middle strips gets less, I'm sure due to reflection. Seems like solid numbers. I'm sure adding a t5 to the outside would be perfect.

I am setting up another frag tank in my garage. I currently have one tank in my garage that uses t5's and I would love to use the same fixture on the new tank but feel I can not. With my garage door closed, hot Florida weather combined with the heat from my current t5's it gets very hot in the garage. It gets so hot some days that my current fixture starts to dim to try and cool it's self. I am wanting to avoid adding even more heat with t5's so I am going to go with leds on the new tank.

The new tank is another Low Boy frag tank. The tank is 48" x 24" x 8". The light options that I'm considering is 4 radion xr 15's or two of the Orphek Atlantik V 4's.

After watching the BRS video on the Orpheks they seem like one of the best led options available. Whats holding me back on them is I haven't heard much about them. While radions on the other hand you hear a lot about but they have been around a while now.

Thoughts on light options?

When your ready for a chiller go with "Trade Winds". You won't go wrong with Radion's but Orphek is better in almost every way except cost. grrrrrr My best advice is to buy the best you can afford after true reseach. GOOD LUCK

Thanks. I have a chiller now. It's the 1/3 Hp from jbj. The chiller is definitely not as quiet as they make it seem.

The heat issue wasn't for the water, as the chiller handles that. I didn't want to go t5 as the garage gets hot and it dims my ATI fixture some days. I imagine two would just make it extremely hot in there.

Yep correct. Also remember you’ll usually have a frag rack 2”-2.5” off the bottom. Plus the frags grow or become a small colony. So now you’re at 3” below the surface. Not the same as 6” as BRS measured.

I was thinking the heat in the garage may be an issue for the leds too. Could put a dent in your par if they are dimming.

Defiantly my bad. Fans like something like these: http://www.frozencpu.com/products/6...hermal_Control_BT12038B1M.html?tl=g36c265s703 or go crazy with this type of cooling: http://www.frozencpu.com/products/1...40_GPX_Pro_AMD_RX_Vega_M01_-_black_11494.html
