@ jeanna

Why don't you build his low current circuit? You have all of the parts for that. I don't think you have lit up any LEDs with only 1 mA yet.

Well xee2,

It was a while ago so maybe you forgot.
I ran 30 leds on 19mA and they were all very bright.
I could have run more but I ran out at 30.

It works out to 0.63mA each. I am not sure, but I believe it is still the record.

@ jeanna

But you were using 19 mA he is only using 1 mA to light multiple LEDs. I am not sure how many LEDs his circuit will light, but it might light 30 LEDs with only 1 mA or 2 mA or 3 mA. His circuit produces high voltage so LEDs need to be in two series strings. Just something you might try.

@xee
Which one is that?
Are you referring to jadaro's circuit?

My circuits usually don't light more than two LED's ...I don't know where to get a whole strand of them.  I'm actually trying to light CFL's, rather than LED's - just because of the high voltage and the notion that it's easy to blow an LED.
