The first sentence of which is, "Compact fluorescent lamps have some
benefits in comparison with classic light bulbs. It is lower power
consumption (to 80%) and much longer lifetime (5 to 15 times).

Longer lifetime my arse. I have tried several makes of these, and
while they have all produced some light for a long time, they have all
become unusably dim by about twice the life of a tungsten bulb - I've
been comparing them in a hallway and living room, each of which has
two sockets.

None of them has anything like the life of the GEC long-life reflector
tungstens I use in the kitchen.

Disadvantages are longer starts mainly at more expensive types,
impossibility to use darker and price."

And the environmental cost of producing and disposing of huge
quantities of electronics, plastic enclosures and mercury.

Thanks for pointing out that page. It demolishes your assertion.

Nice try.
