Hi Steve, Without knowing the power rating of said LED lights then I can't 100% say that the cable you have would be adequate But.... The power consumption of LED's are so small and the length of cable you would need (not very much) would suggest that cable would be completely fine, if anything it would be overkill you you probably get away with 0.5mm2 cable (capable of 3amps) I hope this helps Thanks Stephen
