Class 1 Div 1 Light Fixtures Application

[faresos]

This is a general question, can Class 1 Div I rated luminaires be used in Class II Div I? The certification of this luminaire doesn't mention anything about Class II. I would thought Class 1 Div I requirement is more restrictive than Class II (combustible gases & vapors vs dust ) thus can be used. Any thought?

Thanks,
