    Can I daisy chain 40 4.2W LED lights with 0.75mm 2 core flex.

    13amp plug. rough length of circuit is 10 meters, bulbs are bayonet cap.

    Thanks in advance.

    It's only 162W in total, so well within the operational limits for use at 235v AC, but 0.75mm^2 cable is not robust and we're not taking into account any inrush current which would be a factor with such a high count of LED bulbs. How about splitting the group into 4x 10 and do it on 1.0mm^2 and sleep better.

    Others may have better ideas on this.
