Append the collection of the light that you want
Install the addon and go to the navigation panel in Flotters Tool and add the light that you want ^^
Thanks for your support
Cycles (might have issues) :
Increase the amount of transparency bounces to avoid the ray to be completely black.
(12 seems to be a good value depending on the ray density)
Ray settings are on the geometry nodes on the ray emitter object and the light color is on the material or the ligth.
