Advanced lighting parameters for Cycles Render?


I’m totally new to Blender and Cycles.
At the moment I’m trying to transport my three.js scene into Blender and render it using Cycles. Three.js has a bunch of parameters of lighting: Intensity, Distance, Decay. As I see, there’s is only one lighting parameter in Blender Cycles called Strength.

Where can I find appropriate light parameters (Intensity, Distance, Decay) in Cycles lighting settings?

Thanks in advance.

One place to look at is the Light Falloff node.
