Cheap light = cheap results unfortunately.
Doubt you will find a "proper" grow light that isn't a suspended type.
It is pretty simple to make up some cross sticks to hang the light from, think bbq rotisserie.
Even grow lights that are white are pretty funking bright, this could be as much of a problem as any purple looking lights.
Best to invest in some decent light blocking window shades/drapes/thick plastic sheeting.
Hope this helps,........
