The HALO 4 in. RL Fire-Rated Canless LED Recessed Downlight uses double steel walled case filled with ceramic fiber insulation to ensure a fire rating for up to 2-hours. The regressed canless downlight reduces glare while providing a simple installation. Fire Rated ceilings require multiple pieces of sheetrock for insulation providing plenty of room for a regressed luminaire. Prior to installation, select color temperature of light output from Warm White to Daylight (2700K, 3000K, 3500K, 4000K, or 5000K) and it is dimmable. The HALO RL Fire-Rated Canless downlight is ideal for new construction or retrofit installations in single family, multi family or commercial spaces.
