If they are so inefficient then where does the wasted energy go?

• xxs 4y ago
  The wasted energy as per usual - heat/entropy. It's just that LEDs are the best we have.

  Where it always goes, waste heat. In the case of LEDs, about 50% to 60% of the power draw escapes as heat. Of course, incandescents are much worse.

    70% near heat would the very very efficient blue leds, properly driven and all. below that, i.e. 50-60 is just theoretically impossible.
