Nowty, have you bricked up your lounge window to reduce heat loss or is there some other reason the lounge lamps are on all day?

I used to be obsessive with turning lights off (drilled into me by my parents), but since LED's came onto the scene coupled with the solar and batteries it does not make much difference. There are times when a heavy cloud comes over and the north end of the house benefits from the lights all day.

I fecked up with my payback estimate of 5 to 7 years as most of the power would be supplied from the solar so its probably more likely 20 years.

Isn't this a time that a serious government would & should negotiate a product licensing subsidising price with the likes of philips in an attempt to hammer down the uk lighting consumption requirements over a 24 month period? ..a bit like the early 2000's CFL bulb rush of old? getting us on a more stable base load that both shores up & reduces consumption.

£10+ per bulb, ouch when you are already using LED's (as the majority are now) is still a ring-stinger.

That's sort of my thinking - the last time i bought a new chest freezer i was considering A++ and A+++, but then i thought that with solar & hydro-electric, I'm actually better off buying an A+ and putting the money saved towards more PV, etc.

i do tend to look at lm/w when buying leds, but i also believe in making full use of what I've already bought to minimise the environmental inpact of its manufacture.
