The E2 Lighting Gen 2 4" ultra-slim recessed LED downlight provides a low-profile lighting solution for residential and commercial ceiling applications. Its five selectable color temperatures—2700K, 3000K, 3500K, 4000K, and 5000K—allow the light appearance to be adjusted during installation. The 9W integrated LED fixture operates on AC100-277V hardwired electrical systems and features a dimmable design for adjustable everyday illumination when used with a compatible dimmer. A built-in 10W emergency battery backup helps maintain illumination during a power interruption. The Gen 2 configuration includes a metal conduit wire for hardwired installation and is designed for canless recessed applications where ceiling space is limited. Its clean, ultra-slim profile is suitable for living areas, hallways, offices, retail spaces, and other indoor locations.
