The cost manufacture and transport does need to be considered as part of the whole life cost.
I'm switching over to LED lighting, but I'm using up all my CFL bulbs first, and waiting for them to fail. I have one room that still has an incandescent bulb that is probably at least 12 years old.
Since it was no longer looking like a 2-minute job, I just did it properly and replaced all five bulbs... so now the total power consumption is 25W, not - and this rather shocked me, since I hadn't really thought about it properly before - 250W, or *a quarter of a kilowatt*. And not only that, despite having an 'equivalent wattage' of only 35W, that's obviously wrong since the new bulbs are *brighter* than the old ones - ie they are more than ten times as efficient, and that's saved energy that was being wasted purely to heat the loft, since they're in the ceiling.

Annoyingly I have no other use I can think of for the redundant incandescent bulbs now - although I won’t throw them out.

The mains voltage GU10s have micro transformers built in which get thrown away each time and yet to find a recycling place for bulbs.
Doesn't the drive to the recyling place use more resources than the recycle value too?
Not easy keeping the planet clean!
Replacing them all with 240V fittings would be a major pain since some of them are very hard to get to in the loft - behind the water tank and under the lowest part of the slope of the roof - luckily the one that died was one of the easier ones. I can live with another transformer or two dying before I have to think about that...

With halogens, it was over a kilowatt!
we used compact fluorescents for years, not very good, and still 7W or 11W each, I forget
the 5W, 6W LEDs now are amazing, there are some crap brands around though that are not bright, or do not last, or are too blue.
I've been trying to buy dimmable ones over the last few years, there are some good compatible dimmer switches available
In the event, the dead 'transformer' proved easy to repair - it is a switch-mode type, and all that had happened was that the output choke had overheated and desoldered one of its pins. I've fixed that, so now I potentially have four spares just in case there is some problem with them being run less loaded. In fact, if I'd just done that before I went and bought the new bulbs I could have not bothered... except for the bit about wasting a vast amount of energy and money, so I'm not exactly annoyed about it .

Or more sensibly, if changing them is a massive pain. If mine had been fitted into a false ceiling rather than straight through into the loft space where I could get at the wiring, it would have been a right one...

The biggest saving I've achieved is by switching to a Halogen oven a couple of years ago. A standard gas or electric oven does fuck all in the first 10 mins except pre heat it's self. By that time a Halogen oven has cooked a frozen pizza using 1100 watts in 9 mins. A full roast dinner for 5 takes 100 mins at 1100 watts with a duty cycle of 80 % on to off during that time. It's the cheapest and fastest way to cook.
Seriously: If you value it, take/fetch it yourself
