Okay, I am starting to get my head wrapped around this project but I still have a long way to go . I have a few questions though: 1. As far as a current driver, how will I know what current I want to use (ie 300mA, 500mA, 700mA, 1A)? I imagine you want a happy medium between the amount of heat generated and the light output you can generate, right? 2. I am totally lost on the concept of dimming them. Bemi0701, you mentioned buying the parts individually so that I can make them dimmable. Does that mean that I cannot use a dimmable driver with the kits from rapidled, or does the dimmable driver replace a component of these kits? Not really sure how dimmable drivers fit into the whole wiring scheme or what part of the power they actually control (current I assume??). Sorry, I am obviously a :lots: when it comes to this! 3. What do you think about this heatsink for a 6 led setup? If I use the thermal adhesive pads that Bemi0701 mentioned would it even make sense to use screws to hold them in place or is this just a good failsafe? 4. What about shielding from salt spray. Do you guys put an acrylic shield or something over the whole setup? 5. I think it would be cool to hang it from a hanger like this: http://reefkeeping.com/issues/2009-04/diy/index.php Do you see any problems with adding a couple more screws to the heatsink so that I can attach wires and having it stand alone as a fixture or would I need to create some kind of housing for the whole setup? Okay, I think that's all I can remember for now. Will probably have quite a few more questions soon though.
