My question, is it reasonable to hang the light a few inches above a
glass top or is it necessary for the light to rest right on the glass?

Mine rest right on the tank rim but would be better a few inches off the
top. I lost the spacers I had that held them above the rim by 2".

Cool. I was planning to hang the light about 2-3 inches from the
glass.
