Is there any way to achieve the equalizing effect in lightroom? I haven't really thought about it and I have used the method you mention to check for halos within photos... (upload to queue, check and delete)....

I just choose a random code and registration, to avoid filling anything in, but the process is much slower than just applying a filter. Does anyone know how I can do this without leaving lightroom?

I do obviously use the "check for dust" within lightroom, but it's not the same at all....
