For me the red and green lights bring out more color in the tank. An exact match is out there somewhere. There must be a name or number somewhere on the unit?

Ok so I know this was an old post but here I am still looking at an aquarium that seems to have a center "spotlight".
I have the 16" LED centered on a 48" 55 Ga. I have 2 48" T8s running the full length to help increase the lighting on the edges.
I still don't like it so now I am trying to find a 2nd LED. The issue I am having is that it is a no name LED and I want to find an exact match so my tank lighting will look even.
Here's what I have maybe you guys know where these come from or can offer some suggestions.
Black body with 3 fans
125 total watts
55 bulbs 3 watts
2 dimmable switches
50% blue
50% white with 2 reds 2 greens

I cannot find the same light. There are plenty of lights that look identical but none have the reds and greens. I have searched eBay and Amazon. Would it still look even to just get another LED with the same configuration without the 2 greens and reds?

Oh and btw the power has been up to 100% for 2 weeks now and everything is looking great. The anemone did scoot back a little once I had it around 75%   He only moved 4" to the left about 3 weeks ago and seems happy ]]> Sat, 15 Feb 2014 17:59:21 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=555110&title=lighting-options#555110 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550650&title=lighting-options#550650 Author: LakeCityReefs

I was able to raise the light 2". It is spreading out a little better. It still is most vibrant in the center. I am going to be patient and see what happens when I get it up to 50% power before I try to supplement the light. If I supplement the light I will probably add a single 48" 6500k T5 attached directly to the hood. ]]> Wed, 15 Jan 2014 20:46:14 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550650&title=lighting-options#550650 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550632&title=lighting-options#550632 Author: Mark Peterson

Many years ago I was at the public library browsing through books about the sea. Since I had never been in the ocean, these series of pictures from an old book by the famous Jacques Cousteau, caught my attention. I scanned the 4 pic series because they give a great visual presentation and make for great instruction regarding lighting, don't you think?

Eric came over last night and we went over quite a few things. The tank is a standard 55 gal with a hood that he prefers to keep. Raising the light fixture would require a serious hood remodel. The good thing is that the light will be great for the next tank upgrade. 

Aloha,
Mark

Mark, where did you get those Old School pictures? A double hose regulator, must be from the 50s or early 60s.]]> Wed, 15 Jan 2014 09:42:08 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550599&title=lighting-options#550599 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550597&title=lighting-options#550597 Author: Fatman

How long is the tank and how many gallons? I just read these posts and missed it, can't find it in scanning through them. I have a 120 gallon 48" tank with 4 72 Watt fixtures over it. They are placed very high above the tank to keep from burning the coral and to enhance the light spread. I get great coverage. It's been up for several months and I'm running the neutral whites at about 20 percent and the royal blues at about 25 percent. Any higher and I start burning things. Some of the more tender coral have been moved into the shady areas of the tank.

Putting an 18" single fixture in the middle of the tank (if it's a 48 inch) will leave you with dark ends. You may try to remove some of the optics from the LEDs to spread the light out. Usual spread on an LED is in the range of 120 degrees.

Hope this helps.

Fat

Put the fixture higher over the tank... it'll spread the light out more. ]]> Tue, 14 Jan 2014 23:30:22 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550581&title=lighting-options#550581 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550573&title=lighting-options#550573 Author: Mark Peterson

What is the fixture brand and model you ended up with? From what you have said and how it looks in the pic, I believe it was a good purchase. My opinion is that t-5's on both sides of the single LED fixture might look strange. It should not be difficult to find a fixture that could be a pretty good match for what you have purchased, placing one over each side of the tank. Be patient watching this forum and ksl.com. Patience is one of the toughest things to learn in this hobby.

Aloha,
Mark

Yes. I ended up getting an 18" 125w led. When you crank it up it stretches to the ends of the tank but in the photo it's only in 20% power. I really don't like the spotlight effect. Now I need some 12" T5s for either side or I will have to wait to but another small led.
I probably made a mistake with an impulsive buy. The LED was $120 slightly used. Retail is $269. ]]> Tue, 14 Jan 2014 15:12:48 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550492&title=lighting-options#550492 http://www.utahreefs.com/forum/forum_posts.asp?TID=68942&PID=550411&title=lighting-options#550411 Author: Mark Peterson

I believe Eric bought something different than what he spoke of in the OP. I have invited him to come over and see my ~200 gal, 7 tank system with its 5 banks of lights:
48" Actinic PC's
36" White-Blue LED's
24" t5's
36" blue-pink PC's
48" pink-blue NO Fluorescent
