Key Features

• 2 in aperture recessed housing for new-construction installations
• IC-rated and airtight — suitable for direct contact with ceiling insulation
• 24 W on 120/277 V supply
• Dimming compatibility: Triac/ELV and 0-10V control (requires compatible dimmer/driver)

What this housing is for

The NHIOICD-220LE4 is a dedicated 2-inch recessed housing intended for new-construction ceilings. It is built to accept Nora Iolite LED modules and to be installed before the ceiling finish is applied.

Use cases include general and accent downlighting in residential and commercial new-construction projects where a compact, IC-rated recessed solution is required.

• Aperture size: 2 in
• Construction type: New Construction
• Designed for dedicated Iolite LED integration

Electrical and dimming requirements

This housing is rated for 24 W operation on a 120/277 V supply. It supports common dimming methods—Triac/ELV and 0-10V—when used with compatible dimmers and drivers.

Confirm that the control device (Triac/ELV or 0-10V dimmer) is rated for the connected LED load and that any external driver or module is compatible with the selected dimming protocol.

• Wattage: 24 W
• Voltage: 120/277 V (multi-volt)
• Dimming: Triac / ELV / 0-10V (requires compatible control gear)

Installation and compatibility notes

The NHIOICD-220LE4 is for new-construction mounting—install the housing before the ceiling is finished. Because it is IC-rated and airtight, it may be in direct contact with ceiling insulation and helps maintain air‑barrier performance.

Pair this housing with the correct Nora Iolite LED module and a dimmer or driver that matches the module’s control requirements. Follow the module and dimmer manufacturers’ installation instructions for wiring and grounding.

• Mounting: New-construction (install prior to ceiling finish)
• IC-rated: can contact insulation
• Airtight: helps maintain ceiling air barrier
• Confirm module/driver/dimmer compatibility before installation

Housing ratings

The NHIOICD-220LE4 carries an IC-rated and airtight housing designation. These ratings indicate suitability for contact with ceiling insulation and for minimizing air transfer between conditioned and unconditioned spaces.

Use these ratings to support compliance with insulation-contact requirements and energy/air-sealing considerations in your project specifications.

• Housing Rating: IC Airtight
• Suitable where insulation contact is present

Before You Order

Confirm the model number and the quantity required for your project. Verify compatibility with the specific Nora Iolite LED module and the dimmer/driver you intend to use.

• Confirm module/driver/dimmer compatibility for the selected dimming protocol (Triac/ELV or 0-10V).
• Ensure new-construction installation planning (installed prior to ceiling finish).
• Use the IC Airtight designation when planning insulation contact and air-sealing requirements.
