    Default Anyone installed 12v internal lighting?

    I'm keen to install 12v circuits in my bedrooms, and perhaps in other rooms. But I am unable to find any reviews or websites that explain all the kit one needs

    I know it is best to get the complete kit, transformer and sockets etc, as a set rather than picking and choosing from different suppliers.

    Has anyone done this, or know of a good web resource that explains in simple terms everything that is needed.

    Also, is a bog standard electrician likely to be sufficiently clued up on this? Or is it still quite a specialist area?

    TIA

    Are you talking about 12v lights (yes, done that) or are you talking about installing a 12v circuit? Two different things.

    To save on eleccy bills (although I realise the kit may be much more expensive then standard 240V), and maybe self-sufficient if and when I install a load of solar panels.

    Um, wouldn't 12V lights need a 12V circuit?

    To answer your question though, I guess 12V bulbs, provided I'd be saving considerably on electricity leaving them on.

    But wouldn't a 12V circuit with bulbs to match, as if the bedrooms were caravans, be the best energy saving option?

    No. You can get them with the transformer in the light fitting.

    The 240v LEDs are rated at like 6 to 10 W so a massive saving already. I wouldn't be buggering about with 12v to try and save a little more.

    All depends on what set up you've already got though.

    I'd do a bit more research.

    As NLUK says, 12V bulbs tend to be on 240V circuits with transformers in each fitting. That way you donít need to rewire your lighting circuit, fuse box and switches.
    GU16 bulbs are the ones youíll see most often.

    If you want to save on electricity, switch to LED bulbs, they use a fraction of the power for a similar light output and will last longer.
    Depending on the lights you go for, they may also fit into your existing fittings.

    The transformers are not totally efficient, they waste electricity, some of it ends up as heat.

    I'm guessing you are putting some 12v panels on a roof, charging some batteries and using this to power a 12v circuit.

    I doubt many people have 12v wiring in their houses.

    The good news is that putting up 12V lights doesn't need the help of an electrician. Unless you're completely incompetent.

    changed all my kitchen ones from GU10 standard to led - they used to go pop every few weeks - had the led's for a year with no problems...
