Intuitively, this makes sense. Did you notice problems getting the solder pads hot enough when the LEDs are mounted on a heatsink? Again, intuitively I expect that it will be much harder with a low wattage soldering iron. All soldering irons reach the same temperature, but high wattage ones do so faster and can maintain that temperature better when lots of heat is being conducted away. Does this mean my 15 watt iron will be a problem? Drat!!
