replacing household lights with LED bulbs, advice sort please

It seems strange to me that a consumable, replaceable item, such as a light bulb, forms part of the EPC rating.Indeed. As I alluded to, above, EPCs are really worth the pixels they're displayed on. They over-emphasise some things, suggest ridiculous remedial actions that you wouldn't see an ROI on in your lifetime, a suggest daft things like wind-turbines that most properties won't support and mark the rating down for having a heat-pump!Not fit for purpose is an expression perfectly suited to EPCs. (However, it does allow you to pick up a bargain if you know a bit about energy conservation)2

Of course, at your first service and first tyre change you could lose all these benefits.

Car makers also took various trims off and taped over openings, to improve aerodynamic performance, for tests.

Deleted_User said:So did you all replace working non-LED bulbs, rather than just buying LED spares and using them when the old bulbs stopped working?Incandescent lamps are such energy-hogs that yes, it's cheaper to throw them away.CFLs are a matter of opinion. I know some people say to throw them away too, but personally I'm letting them expire naturally before replacing them with LEDs.Example:A 60-watt incandescent lamp might have a life of 1000 hours. In that time it will use 60kWh of electricity, costing about £12. Even if it's brand-new, it's cheaper to throw it out, spend £10 on a really fancy 9W LED lamp and run that for 1000 hours instead (£1.80 for electricity, total cost £11.80) .N. Hampshire, he/him.

I just "trickle down" CFLs to places where I only occasionally switch the light on. LEDs in all the mainly lit areas but I still switch them off when I leave the room for any length of time.

What works for us is the Ikea Tradfri system - you buy bulbs and various cheap kit and can then do things such as use their Room Sensors to turn lights on when someone is present in a room then turn off when they leave and no motion is sensed.You can get plug adaptors which can turn appliances on and off automatically/remotely.0

CFLs were a bit of an environmental disaster really. We were forced into buying them as the incandescents were no longer permitted to be sold. The PRC predictably churned out huge quantities of substandard product, and then a couple of years later, LEDs became much better and rendered the CFLs redundant so many/most went straight into landfill, mercury and all1

If you take out all the bulbs, does that get you even higher up the scale 😉🤔
"No bulb" is even more energy efficient, after all 😉
