What I brought in resonance is the led internal electronics.

Strange that even with transformer in between that resonant frequency was kept the same.
How could the nodes and antinodes be the same on the primary side of transformer, because I thought we need to have them at correct places to have a voltage available on the primary of transformer to have output on the secondary coil.
