Is there a difference between Corona Lights and CoronaLightMtl?

Hi All,

Maybe a stupid question but is there a difference between a CoronaLight, for instance a rectangular light, and a plane with the CoronaLightMtl?
I like to use the light material  (I'm a former Maxwell user). But maybe the lights offer more quality, speed, etc. The only thing I can find is the IES option.
I tested 2 interiors and saw no difference between the images and the render times are identical.


Thanks

No, unless the light is a sphere. That is the exception (CoronaLight sphere is much faster)
