My Lumia 5.2 / Jarduino Build

Well today is day one...the lights finally arrived. still waiting on some arduino parts.

I am trying out these lights at my coral farm to see if they will be a viable option for a larger operation. Figured I'd make a thread to help others...and maybe others can help me along the way

Wow you brave. I would be a little concerned with cooling so many 3W emitters packed so densely. What heatsink are you going to use?

Yeah that is a concern of mine. I'm starting with the 4.5" x 4.5" heatsink from heatsink usa with a 80mm fan for each puck. we shall see how cool they can stay!

I just ordered a couple of these 5.2 for a build I'm doing, could you give me a rough measurement of the light chip?

tagging along... I need 5-10 multichip for my build (84x30x24 tank). I just got my first Lumia 5.2 today, seems pretty solid., I was actually planning to put 2 chips on the 12" Maker heat sink

Yeah baby!!

Can you give us the specs on the tanks these are going over? I'm particularly interested in what area you expect each one to cover and at what water depth the frags will be.

1.5" x 3"

The tanks I will start these on are 4 500 gallon tanks that are 4'x8'. And a 120...The corals are 6 inches under the surface on the big tank...Im hoping for a 24x24 area coverage...but we'll see if that's possible or not

Following along...Is this your first time using the Lumias?

What's your strategy for fan failure? I would think that heatsink that small would not be able to handle this chip with no fan.

With corals just 6" under the water, I wonder if you will get more than 24" x 24" coverage while still meeting your intensity requirements.

I think they recommend 2 chips per 24"

From the website: "Expect to use only 1-2 of these high performance LEDs per 24x24x24 area in most scenarios"

So i'm starting with one...like I said though this is to test them out...if I need more, I can always get more.

I was thinking of putting a heat-sensing circuit on the heat-sink...so that if it got too hot it would cut power to the leds. What do you think? Do you have any suggestions or wire diagrams for something similar?

Yeah I didnt use the previous version...and I wouldn't have gotten this one until I saw the array of the same leds Im already using...so it's easily justified for me

Well Jarduino does have the ability to dim LEDs in case heatsink temperature goes to some value. Are you going with individual heatsinks for each puck? Then you will need individual temperature sensors and you will certainly run out of channels on Arduino. Personally I have a fixture using 5 pucks similar to these lumia things. I have 1 temp sensor for the 36" makers heatsink. I am running modified Jarduino code re-written by the guy who designed the shield I am using. The shield controls fan speed using PWM depending on heatsink temperature. A lot of the times my fans are off completely since the temperature is pretty low. Below 82F, but I also don't have the density of LEDs like these Lumia boards. My pucks are only 12 LEDs and they are spread out over a larger area I think.

Yeah the pucks are going to be individuals...so I'm thinking that will get very complex to try and utilize the jarduino for this. I imagine just a basic transistor that only closes at say 180 could be fine...and then when it closes it goes to ground through a resistor? I guess a temperature based pull down jumper? Is that possible?

Got a basic ghetto test system going to see what works and what doesn't. So far a lot of little odds and ends proving to be a pita. But in running on max power for 6 hours now, the temp of the chip is 97 degrees...which is a little high for me...but not crazy, and still well below what could be allowed, especially since this chip doesnt have the deep red leds like the last one.

Great job so far, I'll be following along. What are you using for drivers?

Hey Aqualund! Thanks for your advice via the Pm's! Wanting to follow this build to see how your corals react.

How do you like the jarduino? I'm tossed between it and the coralux storm. How many channels of control does the jarduino have for lighting? Is it a lighting only controller or can it do more like control heaters and such?

I like it a lot. I've never used the storm so I don't know what the comparison is. The Jarduino starts with 7 channels for LEDS...and yeah it can do all of the rest of the controller functions with relay circuits...plus you can customize it if you need something in particular.

I imagine with the addition of IC chips you could have infinite led channels...but ive never done something like that. I dunno...I like how cheap it is, I like being able to customize it, and I like being able to fix anything that goes wrong

I'm tagging along. Just about finished my order and I was wondering if the 180w power supply would be enough for 3 700H ldd's and 2 1000H ldd's. I'm going to be running 2 5.2's?

you should be fine...at max power you will need 3.2A...and that one is a 3.75A PSU.

Cant wait to see it over the tank, what LDD's did you go with? 1000 & 700's? What's your setup per Lumia and what size are the Power Supplies?
