Thanks for the reply Nemo. Would you suggest the Cree or Aquastyle?
How many LEDs would you recommend for a 75gal mixed reef?
honestly i think it depends on what you plan to keep, if you are keeping a fowler the 36 would mostlikely do.
lps and softie 48 leds
sps and intense light requiring sps i would go with 72.
18 per heatsink or 36 per.
if you go with channels, 18 per channel wil be great.
that really comes down to your wallet, cree is better, but aquastyle on a tank your size will get the job done and grow any coral, but how high you hang them and the optics you choose will also factor.
What optic would you suggest. I will barrow a par meter when I decide to hang the light. And thank for the input Nemo.
good news is that I'm back in MD at least. Ordered up some goodies to complete the test circuits. I'm hoping my meter will be back this week so I can finish it. Was due for calibration so had to send it back to fluke or it won't be accepted as test equipment on some of these jobs.
Also sat down with our training engineer (who has a strong background in microcontrollers as well too, far beyond anybody else I've ever spoken with) and nailed down the design concepts of a few other things. Gotta order 2 transformers this week, bridge rectifier and a few other components, but that should make a very low cost, low power VFD. Another thing I've wanted to do for awhile
All right Nemo I have pretty much decided on a 36 led kit. I am also considering building my own controller (Aduiro?). Which driver would you suggest so I can dime the leds dusk to dark. I am also going to put the leds on c channel. Any suggestions on spacing? I have a 46 bowfront.
I remember seeing somewhere that they would solder and assemble for a fee. Does anyone know if that's true?
you are going to need the meanwell drivers for what you plan to do.
If you could theoretically find a digital pot with only 25 ohms resistance then yes.. I'll have the schematics for a resistor array through a 16 channel mux shortly
I have now decided that i am going to replace their drivers with these:
I don't need dimming, but this will reduce the amount of drivers i have on my rig, meanwell LPF-90d-48 since i have 72 leds from these guys, i will only need two drivers vs 4, 3 strings of 12 per driver.
Anyone reading this thread and have a huge tank and are seriously thinking of these, keep in mind that if your tank is taller than 24 inches, you will need to keep the fixture close to the water surface and it would be better to keep the leds closer together to increase par. my original thought of 72 on my tank is just not enough, to cover the entire tank and get good par.
rather than keep adding more bridgelux, i went with some xpg cool white(6)
xpg NW (6) and xml cool white (6), so far i have no optics on the xml's and they are running at 1750 ma, the xp's are at 1000ma, i think i will add 10 more xml's and i'm done.
again this is only for larger reefs, regular systems, nano's, breeders, 100-120 gallon systems will be just fine. if i had to order only bridgelux on my tank, i would have gone with 2x120 led kits. i believe this would have done the job well.
Hey nemo thanks for the information. I have a 300g 31" deep tank and reading through this thread trying to figure out how they will work for me has been trying at times.
My tank is a FOWLR but I may add some corals in the future. Do you think 2x120 kits would be ok for me or is there more to it? Knowing what you know, what should I do to make my 8ft 31"h tank pop?
2 of these? http://www.aquastyleonline.com/products/120--LEDs--DIY-Dimmable-Kit.html ...gg 700 bucks before heatsinks.
This is going to be expensive nomatter how I do it. 300g is 300g. *sigh*
