Engineering reference
Choosing the right IR4 configuration.
Confirm the area is genuinely Division 1, then select the 2 ft or 4 ft body, output package and 4000 K or 5000 K colour temperature. Maes Lighting will confirm the complete catalog number and temperature range for the selected configuration.
IR4 is the Division 1 linear in the IR range. It offers 2 ft and 4 ft configurations, selectable 4000 K or 5000 K colour temperature, and lumen packages from 5,000 to 13,000 lumens. 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 configurations and outputs are documented?
The 2 ft configuration is 40 W with 5,000 or 10,000 lumen options. The 4 ft configuration is 80 W with 10,000 or 13,000 lumen options. Both are documented at 4000 K or 5000 K with a 120° beam.
What operating range should be specified?
The operating range depends on the selected configuration. Share the project ambient conditions so Maes Lighting can confirm the applicable temperature range before ordering.
