Help with lighting layout

[gazdkw82]

Helping a friend out to finish the lighting that has been 1st fixed but the electrician has not returned and cannot be contacted.

I thought I had my head around it but then when they said they wanted dimmers it dawned on me that they may all require neutrals and now I'm doubting I have the right understanding of the wiring.

Iv attached a quick diagram of the cables that come into the box and the lighting layout.

Any help would be appreciated. Lighting isnt my strong point.

You can't put two normal dimmers in series controlling one light because they will be chopping up each other's power supply, and even if it worked if one was turned down the other end couldn't turn it up.

You would have to use either wireless or a 1-wire system where one unit is the actual dimmer and the other two are slave remote control stations for it.
