LED lighting and dimmer

My brother and I have been working on more LED lights and controllers.  We wanted to open it up others.  I am going to put together a build thread with pictures for what we have worked on so far.  We also have a website for the controller  http://openlux.org/  .  Feel free to use it or keep updated.
This controller is geared towards the use of meanwell drivers, either 0-10V or PWM style.
Enjoy!

 

about $50 to $60 is all. I will see if we can do a bill of materials and resources.

 

BOM is up; with most of the resources posted. it could probably be done for less than 50 but with shipping and odds/ends it is 50 to 60 bux.

 

Just uploaded some pics and video of the lights in action. This is the first run on these lights. I can make a video of the controller menus later.. but it is very similar to the AI unit. I am running 60 leds on two fixtures, but i have another two fixtures to put up and tie in. I can see already that this is a HELLA lot of light, and i don't have the lenses on (they are in a bag at the moment). If there are enough people interested in the controller, I could order a handful of parts and probably assemble them.

 

anyone have a PAR meter? Or know of a good CHEAP one?

.. and probably another $100'ish in playing and cost of controller hardwares.

I will post more and try to get some pics up as soon as i have some more time... there is always something to work on!
happy reefing!

 

My fixture has 30 LEDs per fixture (x4)

This pic is without lenses on.  Just the preliminary test run.  I have two more fixtures to tie in yet.
This pic was taken when when i finished the outside shell.

 

Looking back, i got great prices on the main components at the time. I remember buying bulk quanity meanwells for $30 when the going rate was 45 to 55 each. And the LEDs have dropped too. But as technology advances keep coming, these costs will continue to drop, as they already have. seems that there are several places that

 

I ordered some parts, i will have ten boards in a week. I will be out until next wednesday. When i return, look for an update at the openlux website.
