Engineering reference
Choosing the right IR4 configuration.
Confirm the area is genuinely Division 1, since that is what distinguishes this family from the rest of the IR range and it carries a cost. Then check the −20 to +45 °C range against the site, and confirm the fixed 120° beam and 4000 K suit the task.
IR4 is the Division 1 linear in the IR range, and the only one with published beam, colour temperature and operating-range data alongside output. Where IR1 and IR3 serve Division 2 and marine work, IR4 is specified where the classification is continuous rather than abnormal-condition.
Common questions
Frequently asked questions
These answers clarify the selection process without replacing project-specific documentation.
How does IR4 differ from IR1 and IR3?
Classification. IR4 is documented for Class I Division 1, where IR1 and IR3 are Division 2 and marine. Division 1 covers areas where a hazardous atmosphere is present continuously or frequently rather than only under abnormal conditions.
What operating range is documented?
−20 to +45 °C at 4000 K with a 120° beam. Confirm against the site's measured conditions before selecting.
