Thanks for the ideas guys. I'll talk to the manufacturer about the sleeves today Hotline1...

I am feeding the fixtures underground with PVC and changing to K-flex (LFNC) within 3ft for flexibility. I didn't want to install a handhole.

The label on the fixture only states the supply conductors need to be rated 125C electure.

The conduit entry into the fixture has to be sealed with a sealing compound that is provided with the fixture (3M 8882 encapsulant)
