Interesting that the heat sinks would make these weigh more than an incandescent sealed beam! One advantage of LEDs was supposed to be a greater portion of the input power being used to make light rather than heat, No? Even if they drew the same amperage, the LEDs should either be cooler, brighter or both.
More efficient yes. Truly efficient, not so much. There is still a lot of wasted energy that comes off as heat and the LED cant handle near as much heat as an incandescent, so it needs to be pulled away by the heat sink.
