Minimalistic multichip DIY LED build

Here is picture of my diy led

What would you guys recommend for a tank that is 7 feet long, 3 feet front to back, and 2 feet deep? Preferably something that I could dim with an analog Reef Angel. Thanks in advance for your time!
 
Would 4 100w multichips be the cheapest bet? How difficult is it to set up and wire a lumia 5.1? I was looking at some of the builds, and was curious if the work involved require a lot of electrical experience?

Yes it should actualy be very blue but bright. Cool Whites should be predominatly blue green and the royal blues especialy in that number should cover up the blue. However the Royal Blues you mention are 450 to 455nm which are on the UV side of true blue which is closer to 470 nm. Therefore if your eye is sensative to UV light and sees it as purple they could look more purple in to you. I have the same sensativity and with some Near UV lights see more more of piunkish glow than others do. I suggest you have some others look at them and see if they are seeing the same thing.

Another thing is multichipos can be powered various ways dependent how they are wired. Some will allow you to drive each color seperatly. If this is the case with your chips you may want to experiment with putting less current through one of the colors to see if you can balance it to a better color for your eye.

The other possibility is they used a cool white chip that is strong in the red end of the spectrum. With a lot of red mixed with the blue the eye sees it as purple as well.

i had to others look at it lit with me, and they thought it looked purple too.. can anyone recommend a color temp or combo of 1-2 multichip (i dont want to use alot of single LEDs) that would give me a bright white-blue? id like to use 4-6 multichips only over a 40b, idealy 4 of the same color. i like the way MH looks but have only used t5's

for now its fowlr so im not as concerned with highest power output, just nice color, after seeing the 10w lit, im thinking maybe 4x20w would work, might even have to dim a little

This post is mainly addressing Mr. Wilson. I have decided to give one of these builds a chance. I'm currently lighting a display (8' x 2' x 2.5')in my office with a group of AI VEGA Colors and while I love the adjustability I don't like the disco effect at all. I have read nearly every single post in this thread and I seem to have very similar opinions to you Mr. Wilson. I understand you can't give source specifics here in the public forum but I have repeatedly seen you post a basic color layout of the single channel multichip you use for your store displays. Do you have a layout for the multichannel multichip that you prefer with the 660nm Red involved?

I have a 36l x 24w x 15h rimless that I want to use as an SPS system. I'd like to light this with two pendant style fixtures using a CPU/GPU Cooler (I have a good idea of what I'll use I certainly don't mind the crazy looking thing hanging over the tank. I figured that regardless of the number of channels I will be using quality Mean Well drivers using a PWM function connected to a Typhon 4 channel controller to tweak the color/intensity. I'm not concerned with a sunrise/sunset as I'm in my office during peak daylight hours and I just don't need the "cool" factor that badly. 120 or 90 degree lenses attached with thermal silicone.

So I think I have most of it figured out EXCEPT FOR THE CHIP :confused: the "dreamchip" had appeal to me initially but I'm with you on the lack of red spectrum. I don't want the snoozy blue or the sharp crisp white. I think I can find a source for a couple of custom chips but what would be the exact layout you'd recommend for a RWB chip? One of those colored diagrams would be fantastic.

I would look for a Chip that has a neutral white of white chip in the 4,000K to 5,000K range which has a color balance that is slightly to the red end of the spectrum. Then as long as your usng controlers you can balance that chip with your blues to get the color that best pleases your eye.

I personly like a ratio of 1 watt Neutral White to 3 Watts of Royal Blue (455nm) and 1 Watt of True Blue (470nm) and 1 Watt of near UV (410 to 430nm). But finding that ratio in a multi chip is tough so simply look for one with all those colors then you can fine tune the end color with the dimmable drivers to your personal color taste.

this chip has the red, green, blue placed close together that should get rid of the disco effect and with them being that close it should look white.

or this with warm white will give you some of the red wave length

or this one has 660nm (Deep Red) on it

Im looking to DIY a new led light setup. Actually have an old 24x3w diy led.
I switch to a bigger tank ( now 40g breeder )

I would like to know how much multi led to get and color. I read a lot in this thread but im still noob with the multi led.

Is 4x 20w would be enought? or should i get two cluster of 1x50+2x10w? and what color temp to use?

Should i only use hybrid chip ( 10,000k /445nm royal blue ) or a mix of 6500k with 445nm royal blue? Easier only to use hybrid chip but is it be good?

Thank you

my other 2 links did not work lets try it again

this one with warm white will give you some of the red wave length
cree lumia 5.2 - 70w full spectrum 5 channel cree led

and this one lumia 5.1 - 100w full spectrum 5 channel led has 660nm deep red
both at led gb dot com

The RapidLED Aruora puck and the new Lumia 5.2 chip are a step in the right direction. The former emulating the Radion layout and the later a step up from the original dream chip, but I really wish both would have incorporated the ability to individually control each color LED (no reason not to on a chip like these, but hopefully in the next round of development. At least some jumpers would have been nice to select 5 channels or individual color control........

im in the same boat. i dont want to use a whole mess of chips and would prefer multichips for the diy simplicity, i found the hybrid multichips and thought oh perfect, i can just use a few of these over my 40breeder. couldnt find a much pictures (or any) so i just spend like $10-12 on one 10w hybrid multichip and a driver from ebay, but the color is a little too purple for my taste. im not obsessed with getting the full spectrum because its a fish and rock setup so im shooting for 14-20k color temp multichips now(i guess 20k multichips apear more like 14k MH), from what i read they closest match the metal halide white-blue im looking for. hope this helps ya ? maybe china will start making more veriety hybrid multichips

if you do 6500k + 445nm id like to see it

Your old set up 24X3 is what I'm running on several of my 40 Breeder Frag tanks. The only exception is I'm running 16 Chips at 4.5 Watts (4 Neutral Whites, and 12 Royal Blues, with 8 Chips at 2 Watts mainly 4 True Blues and 4 Near UV 420nm. Total wattage is 88 compared to your 72 if your running your chips at a full 3 Watts each.

Keep in mind that mine are coral Frag tanks so I'm looking for growth more than color but both are superior now to what they were when I was running 234 Watts of T-5's.
 
does anyone have an opinion on the new lumia 5.2 i am thinking about abandoning my current plan and going with the 5.2 or 5.1 over a 24 x48 x12 shallow tank
