I did not mean to give the impression you could get "pulsing" from a dimmer
You didn't. Everything you said is gold, IMO. As someone wrote on this board, "Your words have iron."

Two days went by and 19toker45's question about frying his plants went unanswered, so I just jumped in. I'd really like to hear more about his setup, hope he posts again.

The pulsing / PWM thing (as presented by 19toker45) looked like it was gonna get people confused. I'm a firm believer in making this stuff seem more accessible. That's what I like so much about your style, and Weezard's. Anybuddy can cut and paste complicated stuff. You guys understand it well enough to express it in different (less technical) terminology. You can restate the concepts in your own words, which is a common metric for comprehension.

Teaching, IMO, is not about how "smart" you are. It's about how clear you can make ideas (which does have to do with how smart you are!)

I'm sure 19toker understands rectifying AC and is familiar with various waveforms (audio amps = o-scope). But not everybody following this thread does, and, happily, it's not necessary for building an effective light with dimming capability. With the equipment available to me, pulsing @ 1.5 ps might as well be just a theoretical concept-- interesting to consider, but not within my power to pull off. Kinda like the particle accelerator I'm building in the garage.

PWM dimming, though, we can ALL take advantage of. It'd be a shame if folks discounted PWM because they ran into a brick wall with "pico-pulsing."
