re CFLs

i am wondering a bit about the economy of such bulbs. even though i
save on energy consumption using it, i wonder how much more energy
is required (compared to incandescent light production) for such a
sophisticated bulb, along with all the additional toxic processes
necessary to make the electronic components.

Its not a case of comparing one bulb with one, but one bulb with 8 or
10 filament bulbs. The CFLs dont create any extra junk over 8
filaments.

Also the big difference is with electricity use, and this dwarfs any
materials and embodied energy differences.


problems. I once made a high frequency inverter that would strike a
tube with O/c heaters. The tube over about two weeks just went dim
and bluish.

I wonder if there may have been a dc component flowing? If so, turning
the bulb connections round may do it.
