More than enough even if you go and install 14x 36W x double tube of flourescent tubes at WCS, that's only 1008W or ~4A at 230V

With the usual spec of 1.5mmsq cables being laid out at minimum per code, coupled with a modest 6A MCB that's plenty of room left which you won't hit.

T5 don't really last long in terms of the ballast (probably due to heat). T8 LED last longer. Case in point: hardly got carpark tube fail on T8
