Basic questions here.
This is a spec sheet for Slim LED Flat Panel fixtures.

To be installed (not by me, just gathering info) in suspended drop ceiling with plenum space above.
Called rep and they said fixtures are plenum rated. For clarity there's a few questions that remain.

1. Is there a designation on that spec that indicates plenum rated?
2. Are LED fixtures such as this (drop ceiling install/replacement) universally plenum rated?
3. Does plenum rating deal more with cabling supplying the power versus components of the fixtures itself (i.e. driver).
