Low voltage halogen like MR16 not only are more efficient than
the 240v equivalant (GU10) but last longer too. As you'd have
known if you'd ever had them.

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.


LV halogen is as efficient as halogen gets, light quality knocks even
best of LED into a cocked hat.


Ah. Someone else has actually noticed this. I was thinking everyone on
here colour blind.

Your mixing up the horrendous GU10 con with decent MR 16/11 LV
downlighters.


Mr Whisky can and does mix up about everything. Really does show what
spirits can do to the brain.

GU10, mains voltage MR16, have notoriously poor lamp life, extermely
vibration sensitive and rubbish beam control but they looked like nice
trendy LV spots but without those hard to understand transformer things.


Yup. Specially made for those who don't understand lighting. And probably
to increase sales of LEDs.
