If the OP finds an LED with a lower voltage drop than the original, then
it will most assuredly have more current flowing thru it with no changes
to the rest of the circuitry.

The current fed to LEDs is typically controlled and limited for a
reason. There is no reason for you to be correct if said circuit is
one such regulated circuit.

Also, single junction diodes such as that discussed here have
changed very little over the DECADES. The junction threshold voltage
hasn't changed much at all. Do you have any examples?
