Energy Intensity

Light energy determines the total energy of all emitted photons and hence the strength of the caustic effect.

Energy intensity controls the brightness of the caustic effect. The default value is 10 000. Values of 1 000 and lower give a very subtle effect. Values range up to 1 000 000 at which the effect appears as a solid bright light. Photon Energy is distance dependent and therefore larger energy value are required to affect objects further from the light source.

Changing the energy value does not affect the rendering time as it is the brightness of the caustic effect which is changing rather than the photon storage calculation.
