Classifications shown are family-level. Individual configurations within a family can carry different certifications — confirm the exact catalog number against its specification sheet.
Fixture families
Start with classification. Then choose form.
Products are organized by work area and form factor, so you compare only the families that fit your application.
Specification path
Classification is the first filter, not the last checkbox.
Confirm the site’s official area classification and applicable gas, vapor, dust or fiber groups. Then verify temperature code, ambient range, ingress, corrosion exposure, optics, mounting and controls against the selected fixture documentation.
A product family may offer several certifications and ratings. Always match the exact configuration to the project requirements.
Common questions
Frequently asked questions
These answers clarify the selection process without replacing project-specific documentation.
What should be confirmed before selecting explosion proof lighting?
Confirm the official class, division, gas or dust group, temperature code, ambient range, ingress, corrosion exposure, mounting and control requirements.
Does every configuration in a fixture family carry the same ratings?
Not necessarily. Certifications and ratings can vary by configuration, so the exact catalog selection must be checked against the project documentation.
