Came across this. Just found it interesting. Had a spent CFL
flood around and opened it up (with my HF MF tool!). Just about
the same as the pic.

Hey, if you want a schematic and complete app notes for what is
undoubtedly almost the same thing, check out

I'm amazed at the complexity of the electronics in these little
*******s. Recent cheaper CFL's all seem to hum. Wondering if they
are now chinching to make cheaper?

"Chinching"? That's a word I'm not familiar with.

All that electronics also makes CFLs all the harder to recycle. (Well,
not hard at all, if you believe all the greenwashing, and don't see the
hordes of kids "over there" smashing and grinding "recycled" CFLs to
extract useful stuff from them.) Wonder how much that would cut into
their net energy savings if proper recycling were factored into the
equation?

Well, at 75% energy savings and equivalence to at least a dozen
incandescents over their life span, I'd say the answer is little to
none.
