The Atlas Lighting FCHB24-36L is a 150/200/240 watt field-configurable LED Medium High Bay built for commercial and industrial applications. Constructed from high-grade die-cast aluminum with a durable white powder coat finish, this fixture is engineered for long-term performance in demanding environments. It carries a 5 year warranty and is designed to replace up to 400 Watt Metal Halide lamps.
The FCHB24-36L offers three electronically selectable optical distributions — Wide (90°), Standard (65°), and Aisle (45°) — allowing precise lighting control for a wide range of layouts. An injection-molded acrylic lens reduces glare throughout. Note that for Aisle (45°) distribution, lumens should be multiplied by 0.94; for Wide (90°) distribution, multiply by 0.96. Color temperature is field-selectable among 3500K, 4000K, and 5000K to suit the application.
Electrically, the fixture operates on a universal 120–347V input, with a 480V version also available, and features 0-10V dimming for full light level control. It delivers 80 CRI output with long-life LEDs rated for 100,000 hours at L70 (maintaining at least 70% of initial output). Standard 10kV/10kA external surge protection is included, and the fixture operates across a temperature range of -40°C to +50°C (-40°F to +122°F).
The FCHB24-36L is IK09 rated per IEC 62262, certified to UL/cUL standards for Damp Locations, and is DLC Premium Listed — qualifying it for utility rebate programs. All Atlas LED luminaires are independently tested in accordance with IESNA LM-79 and LM-80 standards. Installation includes a standard 3-foot chain mount and V-hooks.
