Pendant light? With most ceilings being around 2.4m, that's going to be a very short drop in most cases.A common mistake among some sparkies.
if it’s above=2.25M it does not need to have a water resistant fitting. A normal pendant is fine.
A batten holder might keeps things high enough, or a gallery fitting of some sort, but agree that IP44 or greater is preferable.
Always considered it strange that the 2.25m is measured from the floor, even over a bath. I've seen baths fitted with legs fully extended and the legs on wooden blocks to help with drainage problems.
