Description

4" LED Square Retrofit Downlight | Cool White Wet-Rated Fixture

The Sunlite 89278-SU downlight is an ideal solution for humid environments where outdated lighting fails to perform or needs frequent replacement. Featuring a contemporary square shape and wet-location rating, this LED retrofit delivers crisp cool white illumination while ensuring peace of mind in bathrooms, showers, or outdoor soffits. It significantly reduces maintenance cycles thanks to its reliable, long-life construction and dimming compatibility.

KEY FEATURES:

  • Wet Location Rated: Installed confidently in showers, bathrooms, or under patio overhangs thanks to complete moisture protection.
