How do I hide an emissive object but keep its affect on the global illumination?

Question

I have some static objects in my scene with emissive materials: Area Light under Stairs

Is it possible to hide them, but still have them cast light into my scene via Global Illumination?

Thanks in advance!

Just set a new layer "Emissive" to the emissive object, then in main camera -> CullingMask un-select the the new layer.
