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

Engineering reference

## Selecting within the CIT4 family.

Where CIT2 and CIT4 overlap in wattage, mounting height decides: above roughly high-bay height, the CIT4 output range is the reason to choose it. The manufacturer confirms ambient limits per application rather than publishing one range — check yours before ordering.

CIT4 shares CIT2's sealed construction and lens options but extends further up the wattage range, which is what makes it a high bay rather than a general linear. The two families overlap at the low end deliberately, so a facility can standardise on one lens family across both mounting heights.

Common questions

## Useful answers before the next step.

These answers clarify the selection process without replacing project-specific documentation.

**How is CIT4 different from CIT2?**

Both are documented across 2 ft and 4 ft formats with similar sealing and lens options. CIT4 extends to 210 W against CIT2's 140 W, which is what suits it to high bay mounting.

**What operating temperature is documented?**

The table directs verification of ambient per application and notes the fixture is heat tested, rather than publishing a range. Confirm against the specification sheet for the ordered configuration.
