CFL Ballast Pic

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 http://www.nxp.com/documents/application_note/AN00048.pdf .

I'm amazed at the complexity of the electronics in these little bastards. 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?

Osram did a study of energy consumption breakdown of incandescent, CFL and LED lamps. (Actually, only 1 of each, roughly equal in light output.) In all 3, near or over 98% of entire life cycle energy usage was from electricity consumption during use. Manufacturing, transportation and (for CFL) proper disposal, all combined, amounted to about or less than 2% of total life cycle energy consumption of each lamp.
Osram makes and sells all 3 of these lamp types, BTW.
