GHL340
4' x 4' Recessed Hinge/Latch Door Frame Luminaire
The GHL340 is a robust 4’ x 4’, 5” deep recessed grid-mounted luminaire, engineered for seamless integration with standard T-Bar ceiling grids. Featuring a high-efficacy 0-10V dimming driver and support for California Title 24 compliance, it meets stringent energy requirements. Durable construction includes a 22-gauge steel housing and a 20-gauge extruded aluminum or steel door frame with secure T-hinges and spring-loaded latches. Customizable options include various lumen outputs, color temperatures (including tunable white), sensors, control systems, and emergency battery packs. This UL-listed fixture is suitable for damp locations and comes with a 5-year limited warranty (10-year available), ensuring reliability and longevity.
