Light is not a bullet. Light has no mass. Light does not "accelerate
downwards like the flashlight".

Remember you wanted to synchronize stuff with this? Light will
propagate towards the sheet from the point of emission, reaching other
points radially outwards, from the point of emission, at c. No
simultaneity this way either.
