They change from all tungsten lighting to all LED.

How much money would they save on average per year on their leccy
bill?

Too many variables to be accurate but as a rough guide I would say if
you have current 60w and move to say 12w LEDs then the lighting part
of leccy bill would approx a fifth of the cost (not including the
cost of the LED bulbs)

Snag with that is it's near impossible to know what proportion of your
leccy bill goes on lighting.


Is there a need to know the proportion? If the question is, how much
money will be saved surely all you need to know is how much electricity
is consumed by the lighting?


I saw a figure quoted the other day.

It wouldn't be difficult to rig up a house with metering for light only
use. Or to calculate it, I suppose.

I was interested to see how much those on here thought they were saving by
changing to more efficient lighting. Especially as few have anything good
to say about CFL.


In my case, I would guess about £250 / year saving.

I tried many CFLs over the years, and only managed to find one or two
that were at best adequate. Most (especially the early ones) had such
poor colour rendition they seemed to make any room cold and unnatural
looking with a green tinge thrown in for good measure. Its odd, because
I find the light from linear tri-phospher florries quite acceptable.

I retired all the CFLs as soon as I found decent LEDs!

One of the things that killed the CFL market was the overstated light
output equivalence figures that were banded about.
