Emitter through AGS or half sphere emitter?

Which will clean faster in V2?
I have some downlights which are spheres and naturally they are about 80 polygons each at least. Is that too many polygons to assign an emitter material to or should I just enclose single planes inside an AGS half cylinder?

I could make a guess, but it would be so much better to see you do some quick tests and post your results.

Why do you want to enclose a plane inside an AGS half cylinder?

He said half sphere.

I think he want the dome to be illuminated and be a source of light in the scene, right?

No, he said cylinder
But anyway, don't enclose emitters and waste time. Why not making the cylinder or hemisphere themselves emitters instead...

Yes I said cylinder but I meant half sphere.
Bubaloo was correct. I want to use those half sphere domes as downlights
I am skeptical about assigning an emitter directly on the spheres because the manual says that multipolygonal emitters reduce performance.
The domes are currently 80 polygons each
thanx for the prompt responses

Then, it has forgot to say not to hide emitter behind other stuff, because it's far more harmful than using a high poly emitter alone

Also, 80 poly doesn't sound that bad... Give it a try

Thanx
I'll post results soon. V2 is coooool.
