boosting lightmix intensity of a light to 100x original value will increase noise. Luckily in the next version of Corona there is "bake lightmix" button that moves the 100x factor from framebuffer into the scene, so when you re-render, it becomes fast again

Hello increase value of the corona light /floor lamp/ from 5,0 to 1500 , and than in light mix set value form 100 to something 1-2 .
