You're correct there is a calculation that includes the fins. You'll find these formulas in the heat sink section of the LED forum.i think its too tech for me
but is AREA " just" the factor and if my heat sync had fins and "mass.." ie. depth not just sq cm's..would that not allow me to use
a smaller area?
like a thicker, 10 circular finned highbay:
i am trying so hard[not hard] to "not" sound like i know anything
but using just sq # of sq cm does not compute..what about thermal mass and yes the fins have sq cm's too
forget me i am in too deep..lol
Yes, I won't bullshit you, it will get fairly technical. Running chips at high watts without the use of cooling fans is not easy and definitely not recommended for those unfamiliar with the technology. See 'thermal runaway.' Running lots of chips nice and soft is much more practical and accessible, but it's substantially more expensive due to the large number of chips purchased.
And because I'm an engineer by trade, I can tell you that having someone REAL to talk to if warranty issues ever arise is well worth paying extra for! That feature in and of itself helps guarantee that things will be built right in the first place, if you think about it.
One very good reason to go with a panel like TastyLED is that all of these factors have already been solved for you. Just mount it at the proper height, plug it in and grow.
