There are 12v two LED strips with a wall switch for each. The idea is to have one LED transformer feeding the two. Transformer -> 2 gang light switch -> an LED strip on each gang. The switch will switch 12v not 230v. Anyone got any comment on this. The men at the counters in shops all say a transformer needs to be on each strip, probably trying to sell more. I see no reason why one transformer that is big enough cannot be used.
