Problem.
The buyincoins plates run warm as-is. Without doubling dissipation area how is heat going to leave the plate. Something does not fit and it is not minor.
How much heat gets generated depends on a few things, mostly how efficient the LED devices are and how the current is controlled on the modules.
The 4.5W modules I use have 1 resistor per 4 or 5 (I forget) LEDs. And they are rated to a max voltage of 15V IIRC. If modules are rated to higher voltages (18, 24 or 32V are out there), they must use more resistors to drop the voltage and thus they will be less efficient and create more heat. They will also output less light when run on 12V.
Most people don't know about this and don't care, but in our application having a module that is designed specifically to run very close to the maximum voltage in the trailer makes for the best operation.
