Would LED bulbs be any use instead of 12V spots for saving energy?
My bathroom and kitchen has spotlights, but these are 12V, from a transformer. I was going to replace them with LED spots to save power, but now seeing they are 12V, I assume most power is lost through the transformer anyway? Is there any point me replacing them?

The LED replacement for a 35W/50W 12V OR 240V bulb will consume something like 1.5Watts.
You may therefore have a problem with the transformer simply because there is too little load operating from it. I'd personally ditch the transformer and buy replacement lampholders to take a 240V bulb.
See bottom of this page for what I mean:

LED or light emitting diode, actually uses zero electricity. Power is lost only through the circuitry and wiring.
You will need a transformer, so it depends on how many you plan to run on how cost effective LEDs would be over 12v or 240v bulbs.
Another plus is that LED bulbs like the energy saving type, have a very long working life. They do produce what is nicknamed flat light, ie. light that does not focus, but a couple of 12LED lights in a bathroom would be quite bright.

LEDs use less energy when compared to the traditional 12V. The traditional light bulb losses a majority of energy through the heat which it releases. (Like the toy ovens for kids which cook) LEDs however do not produce so much heat which reduces the amount of energy loss.

LED lights are much less consumptive of power. Our police cars are going to LED lightbars because the traditional rotators and strobe bars use much more energy. If it makes that much of a difference in our cars, it should be good for your house also. The LED lights are pretty much the way of the future in flashlights, car turnsignals, taillights etc.
Consider yourself ahead of your time and it saves energy so there's a double bonus and bragging rights!

Transformers are very efficient: little energy (or power) is lost. LEDs use about 90% less energy than filament lamps. So energy-wise it would be worth your while replacing them.

If fee is a substantial ingredient then CFL's are a extra acceptable thank you to circulate. They extra healthy into maximum lights furniture and are much less severe priced then LED. all the LED lights i've got seen require new furniture and the bulbs are very high priced.

Not really the power consumption is to little to mention.
