Yes, but what I said with a NST and LEDs is 100% true, I have seen it done. No dangers involved besides somehow a dead LED if you happen to have a ma higher than 30ma.

Not counting how to handle a NST but anybody who has one knows that part.

If you're feeding 15000V and 0.03A into an LED, and expect it to light up normally which is about 15 mW of light, you'd better have a heatsink capable of dissipating 450W of heat because that's how much energy is wasted.

Just in case you do not know, my soldering iron's heater element disperses 35W of heat. Do the math. :D

Not sure. My iron is 45W :p But, I have put a LED on a 12KV 60mA for 5 mins solid, just a 5mm led, and it didn't overheat...I had that along with a few arc tubes, but voltage reading at the LED was still about 900 after the arc tubes.

But hey, now you know what a diode looks like if you could really run it to get THAT hot =D

I thought microwave transformers were more like 1500v 500mA+. (750W+)
I think the neon transformers are 12/15kv, 30/60ma.

Obviously be very careful, you can die instantly at that current.
I tried it once or twice, but decided not to play with it any more.
Arcing drew so much current, all the lights in my house dimmed.
Puts out wicked amounts of ozone, neon transformers make way less.
Danger all around, lol.

Awesome pic though! :)

An LED will take crazy HV abuse. You can discharge several hundred kV of RF from a tesla coil through a LED, it will light up and will probably survive the experience. Nice roasting job on that LD with the MOT, by the way!

I appreciated this little break from the norm.

Thanks jbtm!

No, Microwave oven transformer are about 2kv-2.5kv each, and current varies depending on if you have capacitors or a ballast.
And Neon transformer super vary, I have seen them from 1kv 4ma - 15kv 128ma

Just figured I would help you understand them a little better

Dude, I know =) No lights in my house dim, they are all on their own circuit breakers. But I mess with 2 mots stacked. I also have 2KJ capacitor banks, Tesla coils that do 26" long arcs, All my stuff is "Death when touch" I knew this for long time, but that doesn't stop me from doing any of this, or buying pole pigs or 20KJ maxwell discharge capacitors.

Morgan, Your welcome. I just had a dead diode and thought, "Lets arc it!" Did so, and decided it be fun to put it on the forums just to at least show what happens to a diode when it's arced by a 1000 some watt microwave transformer. Was lots of fun =D
