In a test I found the phrase
Sie ist voller Licht
which meant (it was said) she is full of light. I do not undestand voller in this context. Pons says it is an Inv. adj., which, in fact, adds to my confusion. Langenscheidt writes voll(er) with no indication about the use or not of the er ending.
Voll(er) in this case means "voll von" (full of). The -er is entirely optional, "Sie ist voll Licht" und "Sie ist voller Licht" are identical in meaning. Thus the lack of indication in the Langenscheidt, there is no rule. In this specific case, "voller Licht" is used because "voll Licht" is hard to pronounce because of the adjacent-but-distinct "l"-sounds.
According to both me and the Duden, it's a preposition.
