Emssion texture rendering not working properly

Im trying to render in cycles, everyting elese looks fine but the models that are emission texture comes out weird, any idea why this is happening??

That looks like a de-noising issue. Try turning off de-noising and see how that works.

Or failing that, try turning up the quality of the glare node.

Try intel denoise. The vanilla one can cause fireflies to go haywire.
I would also use area lights for the actual lighting here, relying on emission only for camera. Lighting with many emission meshes is usually a no-go for me.
