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

https://straitslighting.com/wp-conte...S-SL917SR).pdf

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).

Thanks
