According to Osho, the formless Supreme is the same in everyone—including Krishna. In Krishna the divine light appears fully because all veils have fallen; in us, layers still obscure it. There is no difference in the light itself, only in the coverings. Thus Krishna is not a different God, but a completely uncovered manifestation of the formless.
Yes: it's the same light; Krishna's lamp is uncovered while ours is still covered.
