I was never stupid enough to have them, which is why you rarely see them
as most get them removed. On paper they are more efficinet but most
mount them in ceiling as downlighters where they can;t be cooled
properly so there lifetime seriously reduces. Which is anothe rreason
you don;t see them much now.


Explain how that is relevant between low voltage and mains halogen?


because LV halogen is being replaced because it;s not as good as people thought it was having to use transformers whch usually go placed where you couldn't get to them.



But thanks for confirming you've never look at them.
