I need some help with the definition of low density cellulose. I need to install a surface mount fluorescent, however the fixure has a label that states not for use with LDC. The ceiling tiles are brand new fire resistant tiles. I know the old staple-up tiles were LDC, but what about the new materials? Can I just leave a 1" gap and still comply?

You sure cannot go wrong in any shape or form with a 1" gap.
