RT8SX

Surface Volumetric Lighting

by Lithonia Lighting

2RT8SX is designed for applications that require the energy-efficient delivery of comfortable volumetric light from a surface-mount fixture. The shallow-depth design of the RT series is ideal for retail, commercial and educational facilities that use a non-grid ceiling system or applications that require surface-mounted volumetric lighting. Certain airborne contaminants can diminish integrity of acrylic.


Construction

Rugged, steel reflector with embossed facets. Painted after fabrication. Door hinges from either side.

Housing formed from cold-rolled steel. Plasma seam welded corners provide a clean finish and eliminate light leaks.

Optics

Delivers volumetric lighting by filling the entire volume of space with light, delivering the ideal amount to walls, cubicles, work surfaces and people. Luminous characteristics are carefully managed at high angles, distributing just enough intensity to deliver the volumetric effect. Regressed, two-piece refractive system obscures and softens the lamp and smoothly washes the reflector with light.

Linear faceted reflector softens and distributes light into the space and minimizes the luminance ratio between the fixture and the ceiling.

Mechanical cut-off across the reflector and fresnel refraction along the refractor provide high-angle shielding and a quiet ceiling.

Sloped endplates provide a balanced fixture-to-ceiling ratio while enhancing the perception of fixture depth.

Electrical

Highly efficient T8 electronic ballasts, Class P, thermally protected, resetting, HPF, non-PCB, UL Listed, CSA Certified, sound-rated A+.

Installation

Lamps accessed by unlatching trim and allowing door assembly to hinge open. Ballast is accessed from below by removing channel cover.

Suitable for stem or cable mounting. Consult factory.
