Why Fire Rated Recessed Lighting Matters​


In commercial buildings and multi-family homes, fire-rated recessed downlights aren’t just an option – they’re a code-mandated safety essential.
Unlike standard slim LED downlights, these fixtures integrate ​fire-rated housings or fire-rated boxes that block flames/smoke for 1-2 hours (per ASTM E119/UL 263),
protecting ceiling cavities during emergencies.
