View Full Version : Please help, cant decide. Leds on 300DD

01/29/2012, 01:45 PM
I have a 300dd 72x36x27h.
Lightly stocked but adding more sps, lps, and softies.
Been looking at apollos both dimmable and non.
Mazarras and AI's.

Problem is $1200 price range. If something was perfect I could go a little higher.
For exampme was looking at maxspect mazarra tripple pod system for $1500.
Looked awesome but dont look like it would light whole tank.

Tank has 3 sections 36x24 so looking at 3 lights.
Apollo ultras are at top and perfect price but now looking at dimmable for a little more.

So what ya think? What else could I do?

You are going to need a minimum of 8 AI lights.

8 wouldnt fit right. Its got 3 sections.
I dont need 300 par on the sand in the corner. I just need enough to light the tank with some sps on top and lps and softies mid and bottom.

Any pics of the tank?

This my tank currently. Has 3 MH on it but one on right burnt out couple days ago so tank is dark on that side. No corals currently over there anyway.

Anyone else?

6 Ecotech Radions.

6 Ecotech Radions.

That only misses my budget by about $3000.
Thanks for the reply though

I set one 300DD up with 12, four on each section and after the Radions came out I set up one with 6. Both layouts work great.

Look into the ecoxotic 100w cannon, suppose to b a 3'x2' spread. u could start with 3 cause of your budget. Maybe a vho in very front and back to eliminate dead spots

I thought about going LEDs on my 300DD, but after looking into 6 $500 lights I stayed with Lumenbright reflectors with 250w MH. You cannot make it with 3 and with the two braces nothing else will work. It will take you about eight years to make up the savings in lamps and electricity if your cost is 10 cents a KWH

Probably a whole lot less than 8 years when you factor in not changing bulbs.... and 10 cents is CHEAP. I wish I lived where (or when) that was true.

The adjustability is worth the premium alone anyway. 3 AI is not even remotely reasonable on a 300DD though. I have two on my single wide 36" tank and could use one more.

Yeah LOL, Radions would be somewhat of a budget buster for you. The only advice I would give would be that if you are buying modular lights you could buy the minimum of what you think you need see how they look and add more if necessary. I have the little brother of your tank, the 150DD which is essentially half your 300DD, and I'm pretty happy with the spread of just two Radions. I was concerned with only running two on my 150DD because of the depth of 27" and the front to back dimension of 36" so I used a VESA LCD multi arm mount to be able to play with the positions to suit my needs. The 27" depth isn't so much of a problem because with the tank's frame and glass thickness taken into consideration it's really only like 25", and figure a few less with sand/crushed coral, and the Radions coverage overlapping seems to make for a pretty good fill. When you measure the inside it's more like 34"x34" and the back corner is occupied by the largish corner overflow, you have two, so I'm probably going to stagger the lamps somewhat as I don't really want to illuminate the overflow box anyway ;) Here's what it looks like over the empty tank:


I'm not pushing you to run Rads because they will kill your budget, even though 4 might be able to cover yours, just that there is no reason you can't see what it looks like under minimum requirements and then add more if needed if you go with AI or something similar. It really depends on how you want your rockwork to be as well. If you plan on big open areas, something much easier to pull of in a DD tank, you could end up using much less light than you think.

The apollo ultras can cover a 36x24 area so was thinking of doing 3 of them. They put out ridiculous par so i can raise them up to get plenty of spread and still have the all the par i need. They look pretty nice and if par was an issue if i go with the dimmable ones the par jumps even higher.

Not top of line but good quality nice looking and american made.
