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 Quote:

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 |

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 |

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? |

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 |

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

and as far as optics most are only running them on the whites no need to run them on the rb ,but i would still order a few extra for beackage or damage

FLGirl....what drivers (power supply in your post) are you talking about? Depending on this the answer to you question differs. In general though you will be wiring series-parallel. Each string of LEDs will be connected in series positive to neg, pos to neg .... +-+-+-+-+- etc. Then each string end will be connected together in parallel...all negatives at one end ------ and all positive at the other end ++++++. Then the driver positive gets connected to the positive ends of the strings and likewise for the negative. How many in series and in parallel is entirely dependent on the drivers to be used. This is critical.
As for the same type of LEDs in each string. Not entirely true. The important thing is they run at the same current. If the current is 700ma such as will be used on the FEDYs then you can not run a different LED rated lower than that with out frying it. On the other hand a Cree RB will be happy to run at 700ma along side the FEDYs. Hope that helps. Quote:

I take it you have to have a seperate power supply for the rb strip to be able to program it for dusk to dawn? If so there wouldn't be that many lights on that circuit correct?

I should get my new power supplies tomorrow or Friday. Here is a quick picture showing the LEDs with some lenses on

So I want to build a 72 inch fixture for a 225 with 31 inch in depth,I was thinking of 40 whites to 20 RB LEDs per 24 inch section,does that sound right? I am new to the configuration and would I be able to use the same drivers they have with the crees so I could place it in back of the heatsinks. Thanks in advance.

small buy led driver like this 85W constant power supply with 4.2A, 15-20V . only using that for 15rb on center bar large i never read a detailed quotable description for the large as I did with the small but did catch that a 220 was returned for a 110 and that it powers 88 leds 11 in series and 8 in parallel.

Thanks for posting that info. I was missing some of that electrical detatils. Did you also get the drivers/power supplies. What are the specs on the large. The small is
85W constant power supply with 4.2A, 15-20V but I never got the large. |

I have to crash right now but FLGirl you cannot use that driver for 15 RBs. The range is 24-30 LEDs but the key thing is the Current output is 4.2 amps and you have to get that down to the individual LED rating by wiring in parallel and for these LEDs thats 6 strings. Divide the current of your driver by the rating of your LED to get the number of parallel strings needed....4.2/0.7 or 42/7=6. I'll explain more tomorrow.
Everyone not familiar with current and voltage please be careful on which driver you select depending on your LED arrangement. There are a slew of Meanwell drivers available here that can be used to accomplish anything you want to do. This 85W driver from FEDY is fine but you have to adhere to its capability which is strictly 5 series connected LEDs in a string and 6 of these strings connected in parallel. And no less than 4 in series by 6 strings else you will likely smoke your LEDs. If you cannot accomplish what you need to with these limitations you need to select a different driver. Quote:
