Are the lights fluorescents, if so check connections in fitting terminals for loose wires, crossed neutral/earths etc.
Even though not on rcd 1/2 of board can still cause rcd trips (well documented problem).
If no faults found try changing fluor. for lamp holder temp. see if fault clears may be duff fitting,
hours of 'fun' to be had on this kind of fault.....
