There's some other options for drivers other than the Meanwell ELN-60-48D. How many do you want to power and are you looking for Dimmable? If you don't want to wait for China shipment I can point you to some options....

Nice build!

I'm hoping they ship something to me right away

its ok some people are just born a**es like yourself ,

Like I said...I just want to make sure someone doesn't make a mistake....and now I am pretty sure you are the 1st one that will burn something down. You really need to consider the 3 points that I made, say 'oh ok' and move on. That or demonstrate how to violate the laws of physics and I'll shup up.

Peace

More fun to watch someone with 12 post get there feathers all ruffled an burnt all out I've wired up way more complicated things then this and I'll be standing here just fine

Honestly my feathers aren't ruffled...I'm actually amused by you. Not sure what 12 posts has to do with simply trying to help you understand...so what, I'm new to the forum. Does your 1082 posts somehow imply you know more, have more knowledge and experience than someone with only 12? Glad you've been successful wiring things and you're right, it doesn't get much easier than this. Problem is you don't understand basic voltage and current and I honestly have only been trying to clear that up for you. Wire it up all you want, pick the wrong driver and it won't work, or you'll smoke 'em or they won't perform. The Wattage output has nothing to do with anything in this case...its simply the product of voltage and current output by the unit...which is all the LEDs care about

Sorry folks, my apologies. Lets get back to the awesome builds going on here.

Ciao

There's nothing wrong with stating something but it's the tone in which u did it/ post has nothing to do with it except it shows your maturity in the way u word your post going back over my math yes it works out at 2.5

I am new to reef keeping. I have not set up my tank yet. I was trying to find the correct lighting set up to be able to grow anything, when i came across this thread. I had wanted to do LEDs from the first and was convinced by people that the technology wasn't proved yet and i should stay away.

I really like the way Jae did his set up and i would really like to go this direction. I have a 60" x 18" x 24". I thought I read somewhere that 1 led would cover a 16sq in area (4" x 4"). Does that mean that 67 LEDs would be enough? That doesn't seem right. Jae has 4608 sq in and 440 LEDs which is 1 per 10.5 sq in; so for 1080 sq in would 100 LEDs be correct? When you are calculating how many you need do the royal blue LEDs count as 1 or are they just for looks?

Those of you in the know would someone please give a formula for figuring out how many LEDs you need. Figuring in surface area and depth of tank and the ability to sustain any reef creature that you can imagine. Is it possible to have 1 light fixture that can be used for any circumstance?

O....... and does distance from the top of the tank have anything to do with that math as well.

I apologize for being electrically inept. I am trying my best.

Oo.......since we're talking electricity how many of you have a dedictaed electrical line to box for your aquarium?


Thank You

imrunnig the same tank when talking with jay he recominded running 60led 3-1 and then 20 royal blue for the pop so 80leds total

 

[funkman262]

So do any of you happen to have an extra 12 royal blue LEDs that you can sell?

 

[josephv]

Im sorry if I confused anyone.My tank has a 72/18 inch surface area and has 80 leds over it,60 white and 20 rb and is very happy.Its perfect for me and my reef.You may want more and I dont think less is a good option.I also have a royal blue strip with 22 leds for night viewing but I personaly like it on all the time.Love the pop!

 

[FLGirl]

BigT ..... what is 3-1. Is that 3 white to 1 royal blue. So 45w + 15rb then a strip with 20rb?

 

[brassmonkyballs]

Really depends on which brand LEDs you use. For these Fedy's 100 seems about right and matches Jaes distribution. Maybe use 80 of these 18000k and 20 RB. If it were to be Crees I would say a total of 60, 36 RB and 24 XPG R5 Cool Whites. But the Crees will cost way more and these Fedy 18000k that Jae found look really good. The 24 XPG Cree will cost more than the 100 Fedy.

Distance from the top of tank only matters so far as the optics used to focus them and allow them to penetrate deeper and so you would need 60 degree optics as Jae used.

Hope that helps

Ok i think i got it.......if I did 3 - 60" x 2" strips put 20rb on center strip and put 23w and 7rb on the other 2 strips making every 4th light rb then spaced the strips 2" apart, would that be an adequate configuration for soft corals lps and sps? Then if I understood correctly get 1 small power supply for blue strip, 1 big power supply for the rest, so that you can turn on blues or main or both. wires, epoxy, and optic lenses....is that about it???

Would I be able to grow acroporas on the bottom of the 24" deep tank

 

[bigt0706]

BigT ..... what is 3-1. Is that 3 white to 1 royal blue. So 45w + 15rb then a strip with 20rb?

yes fl girl , i actually going to add 12 more bulbs for a total 92

 

[bigt0706]

once i get the rest of my bulbs i will post my par readings im also using 60 degree optics on my 1800k as well

 

[Doug864]

Is the ratio of 3 white to 1 royal blue to get the look of a radium mh?
I can place my order once this is known.
Thanks,
Doug

Thanks for the info. I went with 44rb and 76w with optics. I am not electronically savy, but from what I can tell this is exactly what I've been looking for. Low watts + low heat + enough light for coral. I was just about to throw in the towel and go with an expensive MH fixture when I found Reef Central.


THANK YOU Jae

AND

Thank YOU Brassmonkeyballs

3-1 seems to be the combo and then everone is doiing an all rb stip for acsent and dusk to dawn

150 gl LED Project

150 gl LED Project

OK, getting ready to jump in here. Here are my plans, please provide feedback.
I have a 5x2x2 150gl tank, 60" x 24" = 1440 sq inch surface area
97 - 18,000k Whites
30 - Royal Blue
2 - Power supply (large) (30RB/30W on one - 67W on the other)
130 - 60 degree optics
5 - 2-part epoxy

What type/size wire do I need to use? I plan to use my 48" ReefBrite LED strip as a supplement if needed.

What say ye?

 

[FLGirl]

You know. I almost did the same thing yesterday....But mine was more of a wiring question. Guess i'll post mine too.

If we call the power supply the beginning and the last string the end.....will I be joining 3 wires at each string end except for the ones at the last string. 1 wire coming thru the heatsink, 1 wire coming from the previous string and 1 wire going to the next string.?

I read on another DIY LED thread that the leds had to be the same type and qty on each string, is this applicable with these power supplies?

Wire ....... Jae said 20 guage, but the home depot link doesn't work anymore. Is there anything specific about the wire besides "20 guage"?

I know about salt creep.....But I am leaning towards glass between my light and the water surface instead of the sealant.

and I was thinking about going 15" above the surface of the water with the light.........Do you think this will be enough light for ANY type of coral?
Should it be closer?

BTW.......I ask alot of questions......Repeatedly.......please don't hate me too much

 

[bigt0706]

u would want to try and run the same amount leds on the same ballast , 20 guage wire u can run the twisted or hard wire they also sell at radio shack , as far as height u have to play with the height to see what best suits your needs , and yes on your wiring
