Certainly what you say could be correct, but there is no a lot of tests on the theory from you quoted. The LED that I have used, are certainly interesting, and in other this thread experiments more use only Blue or White LED, this fact would be able not to be casual. To the beginning I have tried with red LED array (50 LED with drop tension of 1,6 V), but with nothing  results.

abassign,
Adding capacitor between base and emitter of transistor in parallel with Ceb of transistor should lower frequency. Adding a capacitor in series with resonator coil somewhere else should increase frequency.

@jonesbeene,
How does voltage ever get to 100 volts across LED? Most LEDs only have 1 to 4 volt forward drop. Even when there are many LEDs in series, the drop across each LED is still only about 3 volts.

Testing with resistors may be a waste of time, but it seems like a good place to start. Knowing what happens with resistors provides a baseline that allows me to see how LEDs are performing differently.

Correct - 3+ volts per LED. The effective-voltage can only be guessed, as the power is RF but if the open wire on the secondary will fire up a neon (NE-2) then this is a good indication. If it will not, then your circuit is not optimized. The breakdown voltage for a neon is ~100 volts and presumably that is why DrS emphasizes this particular test, on his web site. It is no accident that the better circuits (more light produced per watt of input) are using 30+ LEDs.

You did study his web site, correct? If you did not then this is highly recommended as your comments tend to give the wrong impression.

OK. fine, if is good to see the "how and why" of it -- but one cannot jump from there to saying or implying, as you seemed to do- that the circuit populated with LEDs is only 30% efficient, for instance. That or any conclusion, when it is based on a resistive load is what is "meaningless" and for several other reasons: most notably the output - BY DESIGN -  is in photons of light. How can anyone say that a circuit is only 30% efficient when they fail to account for the light output?

No disrespect intended, but it is almost like you are totally disregarding several weeks of past work by DrS and others, leading up to where we are today instead, of moving forward based on what has already been done.

@johnesbeene,
I think you misunderstood me. I certainly meant to say that getting even 30% ,as abassign did at first, was way better than what I was getting. I did not mean to imply that was all he was getting.
