    230V LED's

    I came across a 230v LED GU10 lamp the other day which fits into a standard downlighter, how would this work as it is my understand that LED's require a DC supply, if used on an AC supply they would flicker as the Diode only allows current to flow in one direction?

    LED fire rated downlighters - 12v or 230v?

    I apologise if this is a stupid question! What are the benefits of using 12v LED fire rated downlighters, over 230v LED fire rated downlighters? I assumed that this is more cost effective using 12v as although they are more expensive they last longer and use less power, correct? Can anyone...

    230v

    From the transformer as I understand it, it steps down the voltage to 230v (ish for argument sake) and then is supplied to people's homes. How do They design the transformers. If one supplies say 5 houses is it generating enough 230v for 500A supply. I know I don't need to know this. I'm just...

    110v v 230v tools

    Hi Guys, Working in shops and offices. Company is insisting using 110v tools and where possible, battery equipment. I would have thought that 230v + 30mA RCd would be more than safe. Believe that the 17th edition relaxed the rules on 110v tools (55-0-55) Your thoughts gents please.
