RT8 Volumetric Recessed Lighting

by Lithonia Lighting

2RT8S and RT8B are designed for applications that require the extremely energy efficient delivery of comfortable volumetric light from a lay-in fixture that is appealing and shallow in depth and where room-side ballast access is required. Ideal for offices, schools, hospitals and numerous other commercial applications.


Construction

2RT8S: Rugged, steel reflectors with embossed facets. Painted after fabrication. Door frame hinges from either side. Fixtures may be mounted end-to-end.

RT8B: Impact-modified acrylic prismatic refractor. One-piece, vacuum-formed PETE (poly-ethylene) trim with embossed facets.

Optics

Delivers volumetric lighting by filling the entire volume of space with light, providing 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.

2RT8S: 98% reflective Alanod MIRO® silver optical assembly efficiently redirects lamp output to the refractor.

Regressed 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

Standard or high-efficiency, CEE premium, instant start, =10% THD, universal voltage and sound rated A are available as quick ship items.

Optional program-start and step-dimming ballasts available.
