Product Summary
The A4/LED/SH/R/IC/AT is a 4-inch, specification-grade recessed remodel housing engineered specifically for spaces with restrictive vertical clearance. This low-profile fixture installs directly from below into existing drywall or wood ceilings, completely eliminating the need for above-floor attic access. Code-engineered with an IC rating, the housing is safe for direct, continuous contact with thermal insulation. Its ASTM-E283 certified Air-Tight construction effectively seals the ceiling plenum, preventing conditioned air from escaping to cut down on utility costs.
