For those locations where CFLs weren't the bset type there are Halogen bulbs. Their prices are almost the same as old type tungsten. Their life is much longer and they use about 30% less power for the same light.
LEDs are now getting better and their price is falling fast.
I wonder how much those who bought up the last of the tungsten bulbs are faring with their stock, not to mention those who got even more thirsty rough duty bulbs.

The problem was that when tested, the highest power models weren't necessarily the best performers. A bit like old american gas guzzlers.
I am a little puzzled. A few months ago I tried a number of stores in the high street to buy some CFL energy saver bulbs. Very few had them, but everyone seemed to have traditional light bulbs, including the pound shops. The few shops that had the energy savers were charging around £4.50 each. In the end, I bought some on Ebay. It needs to be remembered that CFLs contain harmful mercury that needs to be disposed of at the end of their life.
In the interests of energy efficiency, a lot of electronic equipment now use switch mode power supplies instead of good old mains transformers. They give off a lot of electrical noise and the capacitors in them often have a stated life of about 2000 hours, resulting in a lot of people throwing away failed equipment that could easily be repaired for further use.
On the subject of vacuum cleaners, I think that the bag-less ones are overrated. They are a pain for soon losing suction as the filter becomes slightly blocked. They seem to need a motor of 1500w or above to have adequate suction. I have a recent 800w one that is pretty useless and keeps blowing fine things back that it has swept up.
A traditional bagged Hoover Junior that uses a 250w or 300w motor is a lot more effective at cleaning up and less cumbersome to use, but is not ideal for someone who has a dust allergy, as the bag is the only filter on them.
