LED SPECIFICATION GRADE ARCHITECTURAL RECESSED LUMINAIRE
LTGRF A M I L Y
High efficiency acrylic center lens features a wide profile to provide a softer look that reduces the contrast ratio across the face of the fixture and linear prisms for superior performance without LED pixilation.
In addition to controllable drivers, LTGR luminaires can also be controlled individually with integral sensors or tied into a Hubbell Control Solutions system.

LTGRSHIELDING OPTIONSAcrylic shielding is available in two shapes to enhance interior design and architecture. Linear prisms enhance performance. The lenses are designed for comfortable, uniform brightness without LED pixilation.
Rectangular (R) lens provides crisp edges which quietly accent the curved matte white reflector system.
Curved (C) lens features soft lines which complement the curvature of the matte white reflector system.
LED SPECIFICATION GRADE ARCHITECTURAL RECESSED LUMINAIRE
DESIGNED FOR DIVERSITYMeets a wide range of installation needs while maintaining a consistent luminaire appearance.
Recessed hard ceilings are simple and straightforward with the FK (flange kit) accessory available on all sizes. Continuous row (CR) also available on most configurations.
LTGR offers an optional surface mount for areas where a recessed ceiling is not available. A cable mount option is offered for high or obstructed ceilings where a matching suspended luminaire is optimal.
Slots along the housing edge allow air return to the HVAC when this option is specified. Air return is available in all sizes.

PRACTICAL OPTIONSPractical options for pragmatic illumination.
Life safety compatibility for security and code compliance:• Integral LED NiCAD battery or• Remote mounted Dual-Lite inverter systems
LTGR offers a choice of 0-10V dimming, 0-10V dimming to 1%, Lutron Series 5, Lutron H, fixed output and stepped output for flexible, controls friendly solutions.
LED drivers
3000K, 3500K, 4000K and 5000K corrected color temperatures are well suited to office, education, health care and retail applications. For color consistency across the ceiling plane, LTGR maintains a 3-Step MacAdam ellipse tolerance within the fixture, from fixture-fixture, and over time.
