In this video I show you the positive effect of lowering input voltage and increasing duty cycle (more current flow) to save on input power on series LC tank circuit and end up with same brightness on led's connected to receiver.
As an example my measurements:
953Khz 15%duty 12Vin 0.08A 0.95W 108Vpk-pk
952Khz 20.4%duty 9Vin 0.099A 0.89W 108Vpk-pk
952Khz 38.4%duty 6Vin 0.134A 0.8W 108Vpk-pk
951Khz 50%duty 5.6Vin 0.138A 0.75W 108Vpk-pk
The end result is approximately 20% less input power for same output on receiver parallel LC tank.
