Now, correct me if I am wrong, a halogen bulb is only inefficient if the heat output is waste.  In many applications you do indeed want the heat from the bulb.

I'm going to hope that this will mean that supermarkets will not stock halogen alternatives in their light bulb shelf, but products designed to use halogen or incandescent bulbs for specific reasons .... you should still be able to buy new bulbs?

Also they want to ban fluorescents too.  I don't see that happening.

Because it's 1% of the applications?
Yes, probably halogen will disappear from the supermarket, and you can still buy it in pet shop. Or you might need to buy a second IR lamp.

Also 12V bulbs? That would create a lot of e-junk because all "halogen transformers" (actually crude SMPSUs) would need to be replaced too. They aren't suited for 12V LED bulbs.

Theirs a nice little loop hole in the legislation so good ole incandescent lamps can still be found by using the magic phrases "rough service"
One thing they have also mumbled about,but doesn't seem to be widely reported is the banning of light fittings with non replaceable lamps,that's going to be interesting considering the uk building regs  for meeting energy efficiency either require non replaceable lamps or  use of a lamp base that's incompatible with non energy efficient lamps,are we going to see a sudden increase of incompatibility between manufacturers?

Pet enclosures for reptiles.
Some aquatics / aquariums.
Some hydroponics.
Some horticulture.
Chemistry such as brewing/fermenting things.
Halogen cookers.
Preheating circuit boards for soldering.

Sure some of those could be replaced with a £4000 HVAC system!

Also.  HVAC systems are not the be all and end all of home heating systems.  They only really work in modern homes built in the last few decades and in places where summer is hot enough for the air con function to be needed.

On environmental terms, while an HVAC unit might claim a GOP of 4 or 5, they very often don't run anywhere near that, especially in colder climes in winter.  They have to hit a GOP of 3 to be as efficient as a direct heat from burning the fossil fuel in the home instead of the power plant.

Read the article again. It talks about halogen light bulbs, not heat lamps, which won't be banned.

There are plenty of 12V LED retrofit lamps, specifically designed to work with electronic transformers. I've installed them in my parents' bathroom and they work perfectly.

Here's an application note by Maxim about it.

Very annoying - I have a fan with in built lights and the controller for it does not work with LEDs in, even if they claim they are dimmable
