Thanks for the suggestions.
Webmanny, can you tell me more about this DIY auto dimming LED setup you have?
Sure. I have built about 5 LED systems since I started with my Pico tank a few years back, but I think this is by far the best one I've had and the simplest one to own and operate.
Please note that I love building electronics and I am also motivated by the savings you get when building your own light vs buying one of the new Kessils or Radions or whatever lights are in the market today.
For this build, I bought a heatsink from Rapid LEDs, a fan, a bunch of LEDs, some wire, power supply and a controller. In total, I spent close to $150.00 and I have a fully customizable auto sunrise and sunset light that has been running great for about 18 months now without a single problem.
Since this light is overkill for my tank, I run them at about 60% intensity, which means less heat and longer life on the LEDs.
Here are some pictures:
The light (Don't mind the HOB skimmer, this is an old picture and I have since installed a sump and all new stuff under the tank.)
The controller and power supply:
This is a video of the sunrise and sunset effect sped up X256:

I'll be the first to admit that this is an addiction, because this is the next one I'm already building. This one will be a hybrid with T5 bulbs and LED pucks. I don't know when this one will be done, but I'll open a build thread to share with everyone soon.
