OK, new to this lark but have a basic idea what components do and I can solder etc...
I want to experiment and create some LED lighting for a 20 inch deep, 16 inch across, hexagonal aquarium. I want to use bright white LEDs and a few UV LEDs (helps bring out the colours of some fish). I will be using a project box (with resins to waterproof) but need to know how many LEDs (approximately) I will need to get acceptable lighting. I will be powering with either 12v or 9v (via AC /DC transformed supply through a DC power conector). The exact voltage I will use will depend on the amount of LEDs and power requirments of the LEDs. I may add a switch to independently use the UV LEDs but that is only a secondary idea. Can anybody point me to a schematic or other diagram that my give me some ideas or does anyonyone else have any thoughts.
