They are dependant on the brightness of the light. Double the brightness 
and your caustics get brighter, any other way wouldn't make sense.

You mean you want caustics to be colored, but direct lighting to be 
white? Why?
It could probably be done with light groups, but I haven't done anything 
with that particular feature...maybe a colored light which shoots 
photons at an invisible "ghost object", but doesn't interact with 
anything else, and a white light which interacts with the scene, 
including a "real" version of the object.
The light source itself will only be visible if you use looks_like or 
scattering media.

I'm not really certain what you're asking...it looks like you 
accomplished what you wanted.
