ACUITY 224GP5 GTL LED 2X4 TROFFER120-277V 4000K

Intended use: The 2GTL LED recessed troffer offers a wide range of lumen packages, color temperatures, and lens options to meet the lighting needs for a wide range of applications such as schools, offices, and hospitals. The light engine delivers long life and excellent color to ensure a sound quality, low-maintenance lighting installation. Certain airborne contaminants can diminish integrity of acrylic. Construction: Smooth hemmed sides and smooth inward formed end flanges for safe handling. Lighter-weight fixture allows for safe, easy installation. Optics: Highly transmissive pattern #12 lens diffuses the light source without compromising output. Pattern # 19 and satin white lens options also available. Electrical: Long-life LEDs, coupled with high-efficiency drivers, provide extended service life. 70% LED lumen maintenance at 50,000 hours (L70/50,000). Optional nLight® embedded controls make each luminaire addressable - allowing it to digitally communicate with other nLight enabled controls such as dimmers, switches, occupancy sensors and photocontrols. Simply connect all the nLight enabled control devices and the GTL luminaires using standard Cat-5 cabling. Unique plug and-play convenience as devices and luminaires automatically discover each other and self-commission. Lumen Management: Unique lumen management system (option N80) provides onboard intelligence that actively manages the LED light source so that constant lumen output is maintained over the system life, preventing the energy waste created by the traditional practice of over-lighting. The bi-level dimming option (BLD) allows the system to be switched to 50% power for compliance with common energy codes while maintaining fixture appearance. Installation: LED boards include plug-in connectors for easy of upgradeability. Suitable for direct insulation contact.
