Default Over-claimed efficiency of CFL energy saving light bulbs

Incorrect. In most cases there is now a suitable energy saving bulb.
The number of cases where such bulbs are not suitable has been and
is being reduced.


This of course depends on one's definition of suitable.

I suppose that the change from 95% unsuitable to 90% unsuitable could
be described as a reduction.



At one time such bulbs were really only suitable for relatively
large fittings with lamps that were left on for long periods.


... and that's still the case

This
was because of the size/weight of the bulbs, the length of time they
took to reach full output and a relative lack of robustness of the
starting mechanism.


... no change there then.


However, that was in the early 1980s.


Typo here. Early 2007

The
engineering of energy saving bulbs has progressed a long way since
then.


In 2 weeks?

Come on. Get real. These things are junk and the justification for
them is weak at best.
