im attempting to do a little custom job so i was just wondering if anyone could help me with this, im trying to be patient and plan things out, so can anyone tell me like exactly how big the luxeon 3 watts are... like width-wise, so i will know how big to make my little emitter region, also i was wondering, is it possible to make your own heatsink? and if so, what is the most important feature of the heat sink to include in my custom version?
