Ah, ok. I've never seen/heard it done either. I guess I could get 4, wire em up with one of the adjustable RS dc>ac adapter and crank up the voltage to make them bright enough? I do plan on having 2 blue for moonlighting though.
I ended up getting this sweet rig from **** electronics. I'm cost about the same as a Marineland 24" Double LED light fixture after I got all the right connectors and heat shrink to water/condensation proof all the connections.
Its called OLS LED lighting, about $39 for the main unit with the remote and multi color LEDs. And then $24 for two more 12" LED light strips plus and 12" extention cable. I had to get an cable splitter/extender to get the set up I wanted and that was another $12. So it after taxes and another extension cable for $7 it came out to be around $92.
Its got an IR remote that you can change the LEDs color, fade one color, flash through all the colors and flash red, green and blue. It runs off a 12v power adapter that came with it.
I'm sorry to talk about and not having pictures to explain it and show what I've done, BUT I should be adding water, gravel and my THR by the end of the week so I should have pictures by the end of the week so bear with me!
