Class 1 Div. 2 light fixture requirements

[rey-man]

We have a conduit running from a mudbox to another embedded in a ceiling slab for a lighting circuit.

Below the slab is a Class 1 Div. 2 Area.

Class 1 Div. 2 Light Fixtures shall be pendant mounted from the mudboxes.

What is the proper method of mounting the fixture without compromising the requirements of a Class 1 Div 2 area?

The conduits does not go through the ceiling slab. It is always embedded in the concrete envelope.

Thanks in advance.
