I'm a bit frustrated I want to wire up 2 downlighters which will be independently/jointly switched.

Sparx - Thanks for your promp reply as I said I'm a bit frustrated
This is absolutely a new install. Due to failing eyesight I want to install 2 lights above 2 separate wardrobes with draws in our bedroom, so that we have better visability finding things.
I have identifyed the Power source & my system will be like 2way switching on a staircase - One switch down stairs & one switch upstairs operating 2 separate lights (one upstairs & one down) I have seatched the forum no joy
I want to do the right thing hence my request for help. Thank you in anticipation.

Hi Bill,
OK now I think we can have a go!
I will assume you can get a L, N,& E to a junction box above wardrobes, with 2 sw. one by door and one by bed say either sw. turning both lights ON/OFF if not quite what your layout is I'm sure the basic circuit won't change,
First there will be several connections so at least 6 term box needed.
Run 3 Core & E cable to each sw. position from JB.
run twin & earth to each light, or loop from 1 to other, from JB.
NOW it gets interesting!, connect 2 X 2 way switches making sure you use the brown core for the Com. term in each sw. the Grey & Blk go in L1 , L2, any way round, (should be marked as Brn with sleeving/tape to be correct).
connect lights as marked L,N,E.
At JB join Grey-Grey, Blk-Blk, Bn from supply to one sw. Bn, brown from other sw. to brown(s) to lights. then Blue from supply to Blue(s) to lights.
last all earths together (green sleeved), think thats it!!!!
