to continue & spellcheck!

I tore an article out of the paper recently cos of the title

"Savings on fluoros are not so bright"

A bloke with a lot of time on his hands (& perhaps some techo aptitude) opened up one of those new whizz-bang energy efficient globes.

What he found was "a treasure trove of sophisticated silicon circuitry.

One twisted fluoro tube
5 plastic capacitors
one large electrolytic capacitor
two silicon power transistors
five silicon diode rectifiers (told ya he must have had some techo ability!)
one silicon signal diode
five resistors
one small transformer
one small inductor
one large inductor
one fuse
one printed circuit board & solder to hold it all together".

His conclusion - very expensive to make & as it's heavier than old globes, more costly to distribute, too.
