Here's a question for the group.

Average family living in an average 3 bedroom family house using the
average amount of electricity.

They change from all tungsten lighting to all LED.

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

Around 80-90% of their lighting costs. So, say, 4x 60w lamps on , thats
a quarter of a unit a hour, so what, around 4pence per hour.
Add on a few more for larger houses and multiple fittings in kitchens/
bathrooms, then you'll be up to 20 pence per hour.Average for 4 hours
throughout the year is reasonable, so 4 x 20p x 7 £5.60 a week (seems a
little high?) = £292/ a year.
With LEDS it'd be 2-3p per hour, 84p per week, £43 a year.

Of course, usage will change in every house, I'm at the lower end, other
houses I've been to rival Blackpool for internal illumination.
