DIY Led

It's time for me to upgrade, annual electricity bill, yearly bulb replacement saving and the benefit of LED light getting more and more attractive.
Motive:
Initial cost of my tek elight 8 bulb fixture was $650, since setup changed bulb 2x $480 in total, that's $1000 in 2.5 year

Looking to buy rapidLED 4x 6x9 heat sink for 96 LED in total. Cost with shipping $700, have a potential buyer for my old fixture for $300 with all my old bulbs so after the sale it's really only cost $400.
Commercial made fixture from LFS $1500 with similar configuration.

40x natural white 5w 300L at 75% = 12000Lume
40x royal blue 3w 150L at 75% = 6000Lume
8x blue 3w 80L at 75% = 640Lume
8x UV 3w
368 watt running at 100%

It will run on a custom 32 channel PWM supply, 12 hr/day from 5% to 75%~85%

My current fixture runs 2x54 2hr 6x54 4hr 8x54 4hr 2x54 2hr, 200+1200+1600+200=3200watt 3.2 kWhr for 12hr, I'm calculating this right ?

Lot of question in my minds, optics? arrangement? splash guard? fan? Life expectancies?

That's all for today, will be back, comment's, suggestion's, feedback welcome.

I just built a 108w fixture using Cree LEDs and optics. I recommend the makers led heat sink from led group buy. It comes with fans and a splash guard. I also used invitronics drivers. I haven't had corals under it for long but it sure can make the algae grow.

One, I loved the RapidLED heat sink that was pre-drilled. I would not get the splash guard if you do get optics. Regardless of the LEDs you have, I would recommend you get some kind of optics. I have mine about 8" over my water and I'm using 80 degree optics. The SPS just love the LED but I burned some one of my softies and almost killed off the unkillable-some green star polips because I had it turned up too high to start.

You may also have a much more white looking tank with that much white. I have a a 2x1 3w blue to 3w white and it is still pretty white, but I have chinese knock-offs (bridgelux LEDs). I also don't have my blues and white on separate drivers... so I can't tune it.

My LED's are on the way
Decided to go with LEDGroudBuy instead of RapidLED, both company agreed to give me %10 discount but the final blow was the Heat-Sink, I think the Makers Heat Sink look so much nicer than the pre-drilled RepidLED's.
Talked today a local machining shop and they will die it Red?/Black?/Blue?, the anodized look will be make it even look better.

So it will have 4x 12" module, each with 1xCREE XP-E Red 3W, 3xTrue Violet 3W, 14xCREE XT-E Royal Blue 3W, 6xCREE XM-L White 5W, 1xTurquoise 3W = 72Watt
No optics at this time, will see how it look, close to 300W toned down to 50-75% should be enough and so much less power consumption.

Here is my proposed arrangement for the led's, the Turquoise not displayed cause only got them by mistake, "forgot to remove it from the shopping cart ", I might just stuck it in the third row between the 3 blue's.

Last night I put together one of the test driver, unfortunate the 2 biggest supplier out of stock of this parts "CAT4101" so ordered some sample from the manufactures.
This is just a durability test, ran it for 5 hr above max current with a 20w LED @1.5A
Works great, got up to 62C without fan. Now just waiting for more parts, got to love eBay prices but sure hate the 4 week shipping.

Quick update.

Still working on the software, the main controller will be a ARM based windows ce6 dev kit, finally got it figured out. Each module will have 10ch 12bit PWM up to 1.2Amp, at this time they will connect to the main controlled on RS485 multi node interface, will try to upgrade it later to Bluetooth.
The power source will be 650W Modified PC ATX power supply. The main controller will be able to monitor each led modules fan speed and temperature.
As for now created a small SQL database for the led data, can be update for each led module with 1 minute increment. At this time won't be connected to web nor wifi, hopping to add that later.

Waiting 4 more package of various components from china, 3-4 week shipping but can't complain since I got most of the parts for fraction what I would of paid locally.

Will be updating again in about a week or two.
