hide light emitter from reflecting in mirror

i am trying to light up a room with a model standing in front of a mirror. i used a spotlight which i set the geometry to a disc then set the width and height to 100. when i render, the spotlight emitter can be seen reflected in the mirror as a white disc eventhough i had turn off the render emitter setting. aside from the obvious to position the light so it does not get reflected, is there a way to avoid this?

Use a primitive and make it an emissive with low opacity.
low, like 0.0000001
Though, honestly, you should just move the light. Have it setup so it uses the mirror as the "reflection" onto the model. Then you don't have to be limited to placing it where it is visible in the mirror itself.
Mirror set it to "100% metallicity", and gloss to "scatter and transmit", with reflection set to 100%.
