Thanks everyone!
Dan - i'll pm you with the info you wanted... I can't really say how many to light the whole tank yet, as that's what i'm experimenting with now to find out myself. I know theoretically i can light my whole tank (29 gallon, 30lx12dx18h with ~48 LEDs. whether or not this will provide sufficient intensity is yet to be determined. Each LED runs a max of 3.8v, but 3.4-3.6 is more likely where i'll be running them for longevity. If this all works out, i'll be happy to produce some fixtures for you guys! But for now i still need to experiment, i'd be embarrassed to send someone a piece of junk! Here is my start of the second trial:it should cover an area of 11" X 11" at a distance of 12" away from the light. I am using an identical number of LED's for this fixture as the bar, so obviously the light will be less intense, but i'm not yet sure what intensity is sufficient.. overkill is obviously not a good idea, for my wallet or my tank. Having the leds spread over a distance will also allow the "shimmer" of the water to prevail updates to come...
