Nora Lighting NL4857WW 4 in Square Recessed MR16 GU10 Trim

Product Description

The NORA LIGHTING NL4857WW is a 4-inch square recessed adjustable trim designed for MR16 and GU10 lamp types. It features a white reflector finish paired with a white trim ring, providing a clean, low-profile appearance suited to residential and light commercial ceiling applications. The adjustable design allows directional aiming of the light source after installation, making it a practical choice for accent and task lighting scenarios. Electrical and lighting contractors install this trim as part of a recessed lighting system where a square aesthetic is specified.

This trim is intended for use in 4-inch recessed housing cans compatible with MR16 or GU10 lamp bases. It is commonly specified in residential living spaces, hallways, retail environments, and hospitality settings where adjustable accent lighting is required. The square trim profile suits applications where a contemporary or architectural look is preferred over a standard round trim ring.
