What is the total loading on that circuit - add up the watts of all the lights. And what is the rating on the MCB?

It'll be an electronic ballast, so has a rectifier & reservoir cap input. The result is often a curent spike when switched on. Swapping the mcb for a fuse should cure it, or maybe a type C breaker.
