Light Boost on certain objcets or materials.

Simple question, is possible to have some light boost on certain objects or materials? I don’t mean emission, but if you have scene lighten with lights, on specific objects/materials would have light let’s say 50% more intensity?

Work around is to duplicate number, increase intensity and just light specific layer, but I would like to avoid that. Thanks for any response.

Yes, with using a custom lighting shader.

Can you point me in some direction? I tried google few things but it didn’t went anywhere.
