Lithonia Lighting 2GTL Series 2x2 LED Recessed Troffer

Features & Specifications

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 the integrity of acrylic and/or polycarbonate. Refer to the Acrylic-Polycarbonate Compatibility table for suitable uses.

CONSTRUCTION

Housing formed from 22 gauge cold-rolled steel. Smooth hemmed sides and smooth inward formed end flanges for safe handling. Includes integral T-bar clips. 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. 80% LED lumen maintenance at 72,000 hours (L80/72,000).

eldoLED driver options deliver choice of dimming range, and choices for control, while assuring flicker-free, low-current inrush, 89% efficiency and low EMI.

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. 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 step-level dimming option (SLD) allows the system to be switched to 50% power for compliance with common energy codes while maintaining fixture appearance.

Ballast disconnect is provided where required to comply with U.S. and Canadian codes.

INSTALLATION

The GTL fits into standard 15/16" and narrow 9/16" T-Grid ceiling systems. LED boards include plug-in connectors for easy upgradeability. Suitable for direct insulation contact. Suitable for damp location.

PHOTOMETRICS

2GTL 2 33L LP835, 3399 delivered lumens, test no. ISF 36873P6, tested in accordance to IESNA LM-79.

How to Estimate Delivered Lumens in Emergency Mode

Use the formula below to estimate the delivered lumens in emergency mode:

Delivered Lumens = 1.25 x P x LPW

P = Output power of emergency driver. P = 10W for E10WLCP option.

LPW = Lumen per watt rating of the luminaire. This information is available on the ABL luminaire spec sheet.

MOUNTING DATA

G: Lay-in Grid (exposed or concealed grid)

F: Overlapping Flanged Trim with swing-gate hangers

NOTE: Increased rough-in dimensions for F-trim fixtures 24"x24" (Tolerance is +1/4"-0"). Swing-gate range 1-3/16" to 3-15/16". Swing-gate span 23-3/8" to 26-11/16". Fixture swing-gate points require additional 1-1/16" over nominal fixture height.

BSE Labeling Options

• BSE10: Drivers load transfer relay installed per manufacturer's instructions. Voltage, BGTD and BSE10 called out.
• BSE14: One voltage fixture with driver load control relay supplied with one prewire (PWS option). Prewire wired for normal circuit, the control relay for emergency circuit left unconnected. Voltage, BGTD, BSE14 and prewire called out, in the description.

*For configurations with Reloc or two voltages an RFA modification is required.

Constant Lumen Management

Enabled by the embedded nLight control, the GTL actively tracks its run-time and manages its light source such that constant lumen output is maintained over the system life. Referred to as lumen management, this feature eliminates the energy waste created by the traditional practice of over-lighting.

Without Lumen Management

Energy is wasted and light level is inconsistent.

With Lumen Management

Energy is saved and light level remains consistent.
