FEATURES & SPECIFICATIONS
Type
INTENDED USE — Provides volumetric lighting by filling the entire volume of space with light, delivering
the ideal amount of light to walls, cubicles, work surfaces and people. Typical applications include corridors,
lobbies, conference rooms and private offices. RT5D LED will fill the space with light without glare or cave
effect of traditional downlights. The RT5D LED is 20% more efficient when compared to the mean efficacy
of a common two-lamp, 26W DTT compact fluorescent downlight. The system maintains 70% lumen output
at more than 50,000 hours.
OPTICAL SYSTEM — Regressed, two-piece refractive system obscures the lamp and smoothly washes
the reflector with light.
RT5D LED
Impact-modified acrylic prismatic refractor with polymeric light-diffusing film.
CONSTRUCTION — 16-gauge galvanized steel mounting/plaster frame with mechanical trim retention
integral yoke to retain optical system.
Rugged, one-piece white die-cast reflector system with linear facets softens and distributes light into the
space (ships separately).

Mounting bars are 16-gauge galvanized steel with continuous 2-3/4" vertical adjustment, held in place with
wingnuts. Post installation adjustment possible without the use of tools from above or below the ceiling.
Galvanized steel junction box with bottom-hinged access covers and spring latches. Two combination
1/2"-3/4" and three 1/2" knockouts for straight-through conduit runs. Capacity: 8 (4 in, 4 out) No. 12 AWG
conductors, rated for 90°C.
Fixture height of 4-7/8" allows installation in shallow plenum applications.
Maximum 2" ceiling thickness.
ELECTRICAL SYSTEM — Utilizes high-efficiency LEDs mounted to a metal core circuit board, ensuring
cool-running operation, 3500 Kelvin temperature, CRI > 80.
Patent-pending thermal dynamic control ensures cool running LEDs.
