How come Ohms law doesn't apply when talking about low voltage downlights. i.e 50w divided by 12V = 4.16A so thats obviously wrong. I think Im getting a bit confused.

Probably should not get into this one!:38:It’s raised a question for me. Why the hell are they so popular?
It’s been bugging me for a while, (since I joined this board). They don’t make economic sense.
Is it just kudos on the part on the customer giving bragging rights, (we’ve got these new low voltage lamps in our kitchen, etc). Or marketing gobbledygook by the manufacturers.
As D80 says 50W is 50W + losses. So for 50W with transformer losses of say 1.5% (generous) you use 50.75W.
I thought we were supposed to be GREEN.
If I’m wrong please correct me.
My mate has just built himself an extension on his house to make a kitchen / diner.
He's wanting to put 20+ of these damn' downlighters in it !!! :hanged:
