LTRE

by Columbia Lighting 

Transition® Enclosed LED Deep Architectural Center Lens (LTRE) is an architectural direct / indirect with a curved lens fully enclosing the lamp compartment. LTRE is designed for the health of your occupants, the quality of your installation, the flexibility of your needs, and the beauty of your design. Full distribution light output assures comfortable, effective lighting.
