And oven lamps, and microwave lamps, and other low usage lamps (toilets)

Low energy lamps are not recommended for these uses. They do not like
short illumination.

I guess you'll be required to fit a CFL and a heating element. To
shield the CFL from the element you'll need a dual pane glass
insulating unit, argon filled to meet BS 17459268949475483 for Lava
Lamps. This may only be fitted by an approved Fensa registered fitter
with the extra Lava module NVQ. The result will be lava lamps now cost
£150 and up. Oh, and energy efficiency is precisely the same.

And since the glass insulator seals are found to split in time, the
glass filling with nesting insects, you'll have to have your glass
insulating device replaced every 4 years at a cost of £149.95.

Many things emanating from the EU have been the result of consensus.
If one country objects then it doesn't happen. That is what is
called a veto and it is something the Mad Woman of Finchley bleated
about often.

As the EU became larger so this would have meant paralysis. As a
result for many decisions a change was made to a weighted form of
majority voting, much to the disgust of certain groups of party
politicians. That is the position at the moment.

Are these voting systems democratic? Depends what one means. They
are certainly a lot more democratic than a system where Mr Liar has
a large majority in the Westminster parliament despite less than 20%
of those eligible to vote voting for his political party.

Dimmers are actually highly efficient. All the ones I have do a very
good job of controlling the brightness of the lamps they control.

There is a bit of a clue in the name you know - it's called a "dimmer"
switch not at "energy saver" switch. The purpose is to control the
brightness of the light not its energy consumption.
