Iris Anti-Ligature Semi-Recessed Bulkhead
Iris Semi-Recessed Anti-Ligature Bulkhead is an IP65 and IK18 rated luminaire designed for secure environments where a lower-profile, semi-recessed installation is required. It features the same safety-first design as the surface-mounted Iris Anti-Ligature Bulkhead, with a smooth, decorative diffuser that evenly disperses LED light without any viable ledges for self-harm, combined with heavy-gauge die-cast aluminium construction and a high-output polycarbonate anti-vandal diffuser.
Variant: IRS-AL-SR
