And this raises yet another question for me... what is with the heatsinks for LED bulbs? I thought that LEDs run at lower watts and so should produce less heat yet some of them have heat sinks which the original halogens don't seem to need.

The heat sinks are for the electronics which are required to control current flow to the LED.
Remember that the D in LED stands for diode. A diode is, for all practical purposes, an electrical check valve. Put positive voltage on the output and it will have (more or less) infinite resistance, so no current will flow. Put positive voltage on the input and it will have zero resistance - ie, it will be a short circuit.
