    Hello all - this is my first post on this forum - Glad to be here, hope someone can help.

    I've seen similar posts, but I'm lacking a bit of clarification on whether earthing is required, and whether the existing wiring is up to scratch. We want to replace a single standard light fitting in the kitchen with 4 halogen downlighters.

    The existing light fitting has only 2 wires - blue and red where they connect to the bulb, although black and red where the emerge into the ceiling rose ! The new downlighters say they are double insulated and should not be earthed.

    I am planning on replacing the existing rose with a junction box, from where I will run 2 cables to the first two halogens, and then from them on to the remaining two halogens.

    I was not going to worry about the lack of an earth lead, unless someone on here says differently ! Are there any other potential problems with this scheme that I should consider ?

    ideally there should be an earth present in all cuircuits. but its no huge problem if there is not as the lights are double insulated

    there is also the question of what type of cable to use.

    on the one hand its bad practice to use flex in fixed wiring

    on the other hand its bad practice to have an earth core that doesn't actually connect to earth in a cable.

    id go for the flex myself
