I have a strip light in the kitchen operated from a single switch. I want to replace it with a straight bar 4 spot array. There are three supply cables to the strip light, two of these are 3 core, red, black and earth. The third cable is 4 core, red, yellow, blue and earth. The new fitting has one terminal block with four spaces L, N, earth and spare way. How do I wire the new fitting? What wires go where in the new fitting terminal block
