| 2 ft / 2-strip | Not specified in source | 40 W | 5,000 or 10,000 lm | 120 to 277 V AC; 347 V / 480 V options | 120° | 4000 K or 5000 K | Confirm at quote |
| 4 ft / 2-strip | IR4-4-2-LED-UNV | 80 W | 10,000 or 13,000 lm | 120 to 277 V AC; 347 V / 480 V options | 120° | 4000 K or 5000 K | Confirm at quote |
Confirm the exact configuration against the current manufacturer specification sheet before approval or purchase.
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. The replacement source does not state a catalog number for the 2 ft configuration and contains a conflicting operating-temperature row, so confirm both details at quote.
IR4 is the Division 1 linear in the IR range. The corrected source documents 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?
Confirm it at quote. The supplied replacement sheet contains an internally conflicting temperature row, so the website does not convert that row into a product claim.
