or you could just cut a hole in the mesh that is just a fraction bigger than the light fitting.
Q.did you know that mesh can cut UV rays by up to 95%
95%? Dont know what mesh you have been using but from tests i have seen it is no where near 95% blocked uv, it may be around 10% but having a proper reflector on the tub or uvb spiral makes a huge difference to projected uv levels.
