Weight
Controls the amount of emitted light. It can create noise, especially if the source of indirect illumination is very small (e.g. light bulb geometry).

Note:
Note that a Mesh Light may work better in a situation where you need an object to emit light that casts realistic ray-traced shadows.

Tip:
Increasing the number of Diffuse Samples will help to reduce any noise in dark, indirectly lit areas of a scene when using emission.
