    12V LED strip is configured with 3 LEDs in series per string. At 3V each, the total LED voltage is only 9V, or about 75% of the total voltage. The remaining voltage is dissipated by a current limiting resistor. Since the resistor does not contribute to illumination, we can conclude that in a 12V LED strip, approximately 25% of the electrical energy is dissipated as waste heat.

    In a 24V LED system, there is typically enough voltage overhead to allow for 7 LEDs in series per string. At 3V each, the total LED voltage is 21V, or about 88% of the 24V input. In this situation, less than 13% of the voltage energy is wasted as heat energy.

    In short, a 24V LED system can actually reduce inherent electrical design inefficiencies by more than 50%.
