Light Decay Distance in Cycles

I would be great to control the distance/radius that the light emit it's rays by default. I think this is already an option in Eevee. The setup i used is minimal and it works, but it would be great if something like this was one of the default options of the lights decay_3m.jpg decay_2m.jpg decay_5m.jpg

Not only distance, but attenuation type would be nice too. Its very common in other software to be able to choose the light falloff type

I think it is a similar concept in the end. But yeah it would be very useful!

Indeed! Thanks for the tip I remember trying to animate light coming down the light cone and raylength is the only way to do it in cycles.

Yes I think it will be great if that option was one of the defaults!
