Yeah I never went and researched those questions but there is a lot of information to be had out there on similar builds that you can just do some searching to find answers...I've watched few of youtube videos of similar builds in the past, could be your's I'm not in the know here yet, but a question, is the insane heat-sink absolutely necessary? ofc no harm there, it's just appears like the grey area of people who install the loud open exhaust systems in their cars saying that the stock is choking the engine (engineers facepalm)
1. If I were to build this, would I get away with a passive heat-sink?
2. What is the max operating temperature of that LED?
3. Is the maximum current/voltage determined by the operating temperature the emitter can handle before melting?
3b. If this logic implies, overclock?
All light sources put off heat...now that i look at it again, and it does say 100W, i guess that's sensible, don't understand the false claim that LED produce no heat, i heard that only faulty LED produce heat, because a diode should not have any resistance, so if any diodes are damaged or have been damaged during the assembly - they will create resistance, and heat, is that why they get hot?
