Best type of nightlight? DD having night terrors :-(

[Scherbatsky]

Can you recommend a nightlight for my 22 mo to have in her room? She is having night terrors every night and we put one of our bedside lights in her room and it really helped so now want a suitable nightlight to go in there permanently. No idea about nightlights though, are they all created equal?

My dd got the Disney go glow light which is a torch nightlight and story projector in one.
They sell them in mothercare and Argos.
She is 3 but 2 yo dd2 also likes it
