My LED sps experience shared!

The OG mad scientist
Like many of us , I wondered about this new technology and the aplications to our reefs, specifically as it relates to a SPS dominated reef tank.

I would like to share my experiences with this "not so new" technology and its future.

Like many of us the forums are leaps and bounds from the usual 6-pack and lets talk about reefs afternoon. One of the initial writeup was IMO one of the best that prompted me to give this a try, here's that particular article for those interested.

A little bit of background-- I've been keeping saltwater tanks and reefs since UG filters started yes its been a while, and no other technology besides skimming and reactors has caught my eye more than the LEDS, mainly becasue of the pros in terms of electricity and the endless controllable features that this units provide.

In my case I decided to use the Aquaillumination modules and so far I'm extrememly impressed with thier performance and reliability, as well as the power concumption.

I will post some pics from its inception and like many of us, many ups and downs but finally after many mini crashes and so forth its beginning to take shape.

The LED modules have been running consitently for 4-5 months now and the adjustments as of today have been minimal thus results are starting to show.

Tank was then lit by 3x400 watts radiums on lumenbright pendants
While this has always been my favorite configuration, the heat and power consumtion was way to much and decided then that something needed to be done.

7-24-2010 the decision was made and here we are.

Sps

Sps

Lights are on for 10 hrs
Mid-day the max the units run is at 60% white and 100% blue for two hrs.
The rest of the 10 hr photoperiod the white fluctuate( controlled by profilux) from 10% to 60% but never more than two hrs at 60% white.

The blue settings start at 60% and run for about 6-7 hrs at 100% then randomly change depending on rainy days/clouds passing over the reef and so forth.

That clam looks wicked :) when you say results, I trust you mean ones which are quantifiably positive?

Yes exactly-- there was a typical slow process for the corals but at this 4 month mark they seem to be adjusting nicely to the change and growth has been excellent.
Here's some other random pics.

wow those led lights look awesome , and i see that your sps responding well to that light, good job , keep us posted.
 
do you have any coral pics from when you started to now...to show the growth difference? I think that would be really great to see, as with all lighting, we can adjust for personal visual taste. A friend also just bought the AI Sol...think that is what it is called...looks just like yours...he is very pleased and also runs it at 60%....his profilux is on the way, but will be interested in your thread for the color adjustments that you do through out the day so I will send him the link....
 
I copied this from their website. They do use xpg's(type of led).

Managing your light is a right, not a privilege. The AI Sol exclusively uses white Cree XP-G and blue/royal blue XP-E series LEDs with a combination of our proprietary 40 and 70 degree lenses, balanced specifically to achieve the greatest spread without sacrificing intensity
 
So how much of a reduction in power consumption have you seen?

Have you calculated the consumption of your current fixtures compared to your old?

You should be able to figure out $$ saved per month by figuring the difference it wattage used x KwH charge for your area.

I would be interested to know! I figured out where I live it costs me $7.50 per month to run a 250w Halide for 8 hours a day.

Between two chillers running as well as 3 x400 watts MH's somehwere in the vicinity of $80 or more a month savings.
 
back at u.
BTW coverage for this units depth wise IME would not be much more than 26-28 tops.
On my current tank I'm stretching 28 wide with a couple on inches back and front w/o light loving critters.

There's no doubt that LED'S can grow and make SPS thrive as long as there's good husbandry associated with it.

As close as an example i can give u-- this stag has been fragged 30 times at least.
