Tried the link, says you need to be registered to view the pics. Sounds cool though.

That's cool. I like it!
On a side note, do fish need a day/night cycle? Does lighting affect their behavior?

hi,
I forgot to mention other superheros, namely Mr Photonfanatic and George. This is ain't no ordinary fishtank. it is going to be a coral reef nano-tank. I am overdriving the LEDs @ around
1000mA plus dimming capability. intent to decommission the tired LuxIII in time for K2. /ubbthreads/images/graemlins/smile.gif

Re: LEDs for aquarium Questions
The pictures are splendid. Can you tell us a little about what LEDs are in that disc and how they are set up? I see two tubes at the top, that is fishtank water? It goes over a heat exchanger? The LEDs themselves? That is a pretty small space. Do they share a common heat exchanger? What colors does a reef need to thrive? What colors display it best? Would it be simpler if you simply had the LEDs submerged right in the tank? Are you able to keep them fully cool at 1,000 mA?

Re: LEDs for aquarium Questions
I don't want to rain on your parade, I don't believe that those leds will be bright enough, provide the right spectrum to provide enough light for corals/ coraline algae.
You might get away with some button pollyps, or mushrooms. But there isnt anyway to keep SPS or LPS (Stoney corals). Have you looked into compact flourescents or metal halides???
I think the leds are very cool, and would be great for fish only. But the corals lives depend on light, I just dont think these lights will provide for them.
Please don't take offense, just my .02,

Re: LEDs for aquarium Questions
I have 6 SWOJ and 1 royal blue glued via thermal adhesive.
the tubings are the in/out via a 25G water reservoir.
I find the HE too noisy so I am chilling the warm water via frozen water bottles.
corals will grow damn well under 5500-6500k but its to too yellowish for our liking. prefered 10-14000K. the YO bin is atleast 8000k. you can try but its cheaper to mix around with lower K temp and some nice blues.
If I could get hold of some graphite, cooling LEDs via submersion would be cool.
My main concern is the Tj @ 1000mA. I am not sure if the heat dissipitation is fast enough and whether the die can handle the thermal and electrical overstress. we have to plot and see the degration chart. /ubbthreads/images/graemlins/smile.gif

Re: LEDs for aquarium Questions
I am trying a diferent philosophy here.
I am moving away from pure brawn light.
I will be working more on improving water quality and food chain supply to make up for the loss in light to give our boys a more balanced meal.
my nano will probably need 3-4 modules total. 25W each.
will update as and when.

Re: LEDs for aquarium Questions
Hmmmm......interesting experiment. What invertebrates do you intend to keep and how deep is the nano tank?
I've not used LEDs as the main source of lighting before so I can't say that it will not work but other than the possible long term health implication, the spectrum distributions of white LED will not be able to bring out the vibrant colors of the fishes and other critters as nicely as metal halide lamps or even power compact lamps.

Re: LEDs for aquarium Questions
hi,
Its a 1.5 ft cube. sexy and anemone shrimps. The shrooms are doing fine. Some LPS will be a good acid test.
I agree LED needs maybe another 5 years to match today's MH and FL. I am a sucker for tech stuff and very much someone ruled by the heart. that is why you have this little mod here.

Wish you good luck on your nano and please keep us updated. Did I mentioned that the rock scaping is /ubbthreads/images/graemlins/happy14.gif?

Don't tell me you're the one who put up the signage? Or that I can find those answers at SRC?
Yah, happy reefing too! Have you added any LPS yet? How are the mushrooms doing?

Re: LEDs for aquarium Questions
I thought that you could simply submerge a LED and run it. What would the graphite do?

very nice... made me thinking whether someone has ever done a liquid cooled portable led light...? I have done the fan cooled 3x5W-w bin... wonder whether a liquid cooled would be possible....
