Key Features

• IC-rated, airtight housing for direct contact with insulation
• New-construction mounting for installation prior to ceiling finish
• 12 W dedicated LED housing with 120–277V multi‑volt input
• Includes emergency (EM) driver
• Supports Triac/ELV and 0–10V dimming controls

What this housing does

The NHIOICD-48LE4/EM2 is a dedicated 4" recessed LED new-construction housing that provides 12 W of LED support through a multi‑volt driver. It is IC-rated and airtight, permitting direct contact with ceiling insulation while minimizing airflow between conditioned and unconditioned spaces. The unit includes an emergency (EM) driver for emergency circuit integration.

Where to use it

This housing is intended for new-construction residential and commercial ceilings where a 4" recessed fixture is required and the housing may contact insulation. Typical applications include general illumination, accent lighting, and specification-driven commercial installations that require IC-rated housings and emergency driver capability.

• New-construction ceilings
• IC-rated ceilings with direct insulation contact
• General and accent recessed lighting in homes and commercial spaces

Electrical requirements and dimming compatibility

The NHIOICD-48LE4/EM2 operates at 12 W and accepts 120–277V input, enabling use on standard residential circuits and 277V commercial circuits. It supports multiple dimming methods: Triac/ELV and 0–10V for smooth level control when paired with appropriate dimmer controls.

• Wattage: 12 W
• Input voltage: 120–277 V
• Dimming: Triac / ELV and 0–10V compatible
• Includes an emergency (EM) driver

Installation: new-construction and IC considerations

Install the housing during new-construction prior to finishing the ceiling. The IC-rated, airtight construction allows the housing to be in direct contact with insulation without risk to the unit’s rated performance. Pair with compatible trim and a 0–10V control dimmer rated for the connected load.

• Designed for mounting before ceiling finish (new-construction)
• IC-rated — acceptable for direct contact with ceiling insulation
• Confirm trim compatibility and dimmer rating before installation
