Can somebody help me construct a big-picture view of where I should be turning my attention here. I want to put together a DIY lamp of some considerably brightness, up to maybe 50 W. I'm an electronics noob so I'm looking to start with off-the-shelf kit if possible, at least to begin with. What I basically want is to drive/control maybe 3 different colors of white LED, and be able to dim them all, in a sensible fashion, much as the cheap LED tape controllers provide. I'll settle for physical controls for now but it would be nice to be able to plug in wifi control and an app at a later stage. I've been looking at PWM drivers but the variety is enormous and I lack the knowledge at this point to further refine my searching. What are some ideas for a path to take here. E.g. I have notes on DMX512, Arduino, ? And given I want to drive a lot of power, should I be looking at high power controllers, or boosting power after the controller stage... I realize this lacks specificity but as I said I need some broad overview advice before I can even start thinking about particulars.
