My Lumia 5.2 LED build

[jener8tionx]

I have been working on this light for quite a while now and I promised to upload pictures, so here we go. The light is controlled by PWM from my arduino. The Tank shot at the end is with the light at 40% and is not as blue in person. I have it set to look a lot like my Phoenix 14k 250 MH that was on there before.

Parts:

2x Lumia 5.2 (from the only place that sells these, but whose name appears to be blocked)
3x LDD-750 (from lumia seller)
2x LDD-1000 (from lumia seller)
5up board (from lumia seller)
voltage regulator (from ebay)
48v 5.2A power supply (from lumia seller)
Transistor to control the fan (from ebay)

Wow, that light is awesome. Great build!

What color mix is that? looks like B, RB and White.

What color mix is that? looks like B, RB and White.

Each is a 5 channel array as follows:

Channel 1 - 3 Hyper Violet and 2 CREE XT-E Royal Blue (Actinic channel) (18v @ 700mA)
Channel 2 - Royal Blue (base blue spectrum) (16.5V @ 1500mA)
Channel 3 - 3 XT-E Netural White and 2 XT-E Warm White (base white color) (16.5V @ 1500mA)
Channel 4 - Turquoise / CREE XPE2 Blue (enhanced color spectrum) (17.2V @ 700mA)
Channel 5 - 3 Hyper Violet and 2 CREE XT-E Royal Blue (Actinic channel) (18v @ 700mA)

I run channels 1 and 5 turned down a bit and channel 3 turned up a bunch. I only have 1000mA drivers in channels 2 and 3.

went to the site. That heatsink gives you many options for mounting the leds/fans/supply/brackets. Always good to know all of the DIY options.

The only suggestion i would have is to route the power cables down the hanging bracket to clean it up.

This is such a cool build. I wish I had the skills.

I'll ask because everyone knows how classy I am. How did the cost of this build compare with an off-the-shelf system such as a Radion or a Hydra?

 

[jener8tionx]

There isn't a ton of cost savings the way I did it. Those multichips and the heast sink alone cost about $320. Add the drivers and power supply and my total was around $420 + $30 in misc parts and hardware. I already had the arduino, but those can be had for pretty cheap.

The upside is the controlability. Also, I like these multichips better than anything else on the market. Also, the ability to keep the chips cool with the heavy duty heatsink should prolong the life of the LEDs

sweet looking light. nice photos too. its nice to see pics of how things are connected.

This is actually very cool. Makes me want to sell my Giesemann Infiniti and build one of these.

What size tank do you have and how is it going so far?
