MACNA Speaker on LED`s

It was Sanjay Joshi, and he would not let us tape him, sorry.

 

Troy the new CORAL mag is full of articles on LEDs.

 

My guess is that there are people on this board that have the information you want about LED's and MH's.

 

Agree with BRad, check out the CORAL magazine. Sanjay's talk is published in the recent issue.

 

In summary... As I remember it

Led is close to being as good as mh but most led still lack adequate par at the bottom of a 24 inch tank.
Most led also lack red spectrum.
He was not impressed with the stats of the new ecotech fixture
Vertex, Ai, and maxspect all had good ratings

Led is the way of the future but needs some refinements before it's ready for prime time as complete replacement for MH.

I am sure others can add to this...

I was bummed to hear this wasn't filmed so thanks for they summary.  It was as I had suspected it would be.
That said I'll be sticking to my MH's and supplement with LED's.

 

The maxspect looks pretty nice.

 

I have completely switched to DIY LED I get just as good of growth as MH and I think the colors in my corals pop more under led then MH. plus I haven't ran my chiller since I switched I don't even have it hooked up anymore and it used to run all year long

 

I think LEDs are going to replace all the other lighting, but they are still not quite there yet. I have been doing lots of reading on LEDs and I feel that the multi chip LEDs Will take the lead in the lighting wars to come. They may not have the par per watt as some of the current crees but they will handle more wattage and you will need fewer LEDs to get the same coverage. They will be able to mix colors in the chips to help cover the spectrum of light that the corals need, and with the higher watts they will not need to use such a focused lens or reflector to penetrate the water thus needing fewer LEDs.

 

I also have the DIY LED's and I don't regret it for an instant.

This is starting to sound more and more like the people who used to be convinced that CD's didn't sound as good as records.

Some of my corals clearly like the LED's less but many of them clearly like them more... It's a wash... In any case, I'll gladly trade 5% growth for a 50% reduction in my electricity usage.

 

I agree
There a lot of really successful tanks running under led.
It only going to get better and more refined....

After I get my main tank going again, I will start looking to make the switch.
So far from what I saw at the show I think the maxspect, and and Vertex units look most promising.

I just emailed maxspect about their lighting recommendations for my 90. they recommend 4 and their fixture only site 4 inchs above the top of the tank. i am guessing with a diy mount that will allow me to hang them higher i would be able to get away with just 2. I know with AI 12inch above the water 2 is all i need. What i do like about the maxspect is how you can tilt and turn them to fit your needs.

 

Why not just get two of the AI fixtures and ask about the mount they were showing at MACNA? Less money for the same coverage. If they recommend 4 inches, I think there's a reason for that.

 

I like the look of the maxspect is the biggest reason.

 

personally for that size tank i would consider turning them down 10-15% over all and adjust from there. What is your ramp up and down time? for example how long does it take the whites to go from 0 to 65% and then back?
