Thanks guys :)

The optics are fairly cheap in comparison to everything else.
The heat sinks for the LED's were $120, aluminum light enclosure ( 52 x 12 x 4 ) was $175, main board of the controller was $60 and the daughter boards were $80.
I'm not even going to mention the hours of R&D I sank into it and the $50 or so of SMD parts, but... in the end it will be a cool package giving the end user 24 channel LED Driver.
Yes... I will be selling the units once I have it dialed in and running right.

So you're doing this for yourself or as a commercial venture?

A bit of both...
The Driver will be the venture meanwhile the fixture will be the test. There's also an aquarium controller with full array of accessories on the horizon as well...
