Ordering data

## Every documented IR4 configuration.

All 1 configurations of the family are specified on this page, so you can compare wattages, outputs and options side by side.

| Model | Wattage | Typical Lumens | Voltage | Beam | CCT | Operating Temp |
| --- | --- | --- | --- | --- | --- | --- |
| IR4-4-2-LED-UNV | 70 W | 13,000 lm | 120 to 277 V AC | 120° | 4000 K | -20 to +45 °C |

Confirm the exact configuration against the current manufacturer specification sheet before approval or purchase.

Engineering reference

## Selecting within the IR4 family.

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

## Useful answers before the next step.

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.
