Yes, you can attenuate emissive mesh lighting by adding a LightFalloff node to the strength connector of the Emission node as illustrated below:

Use the Quadratic connector, it attenuates the light, and control the intensity with the strength value on that node. That Blackbody node controls the light temperature in degrees Kevin, you can simulate different types of lights like candlelight to bright midday lighting. Depending on the temperature range, you can imitate LED, incandescence, halogen, etc.
