      All relatively simple boards. I'm interested.

      Here's another: http://coralux.net/?wpsc-product=ldd-5-driver-board. I like the pull down resistor on this one.

      V2 is just a dream at this moment. I haven't been in touch with Alan. Though, I assure you, the v2 concept is awesome. Relatively simple concept too. It should change the landscape again.

      Color mixing lenses?

      I finally got my tank up and running with the 50W dream chip lights. I've built my own controller that can be operated from a web page using my own automation framework.

      However, I've got a severe issue with the optics (60 degree lenses from ac-rc). The lenses simply project an image of the light source. The two "full spectrum channels" are positioned along opposite edges of the light source, and when running one of those channels alone, I can see that the light is concentrated in the front or back of the tank, respectively. Banding is also visible for the other channels, but not as extreme as for the edge channels.

      I've searched the internet for a "color mixing collimator/lens/reflector", that would fit the dream chip, but with no luck so far.

      Does anyone else have experience with this issue and how to resolve it?

      Best,
      Esben
