Lights without reflection influence

[Inscari]

I am interested in light without reflection influence and I don't find a way. This kind of lights are important for lamps and artistic control (1 light for illumination and other light-mesh with the form of the real one for reflection of the scene materials).

I tried to find a way with lights or mesh light setup...

This kind of problem is usually handled with a combination of IES point light (to have the desired goniometric light emission, IES file usually coming from a lamp vendor) and a lamp with shadow transparency (so the geometry doesn't affect at all the light emitted by the IES point light source inside).
