2RT5

2'x2', 2'x4'

Intended Use

The 2RT5 Series is designed

for applications where

comfort, aesthetics and

energy savings are important.

Provides volumetric lighting

for applications such as

oces, schools, hospitals,

retail and numerous other

commercial applications.

Construction

Two-lamp conguration

provides 33% energy savings

when compared to a com-

mon three-lamp T8 system.

Low-prole 3-1/8" depth

makes RT5 ideal for applica-

tions where plenum height

is a factor.

Two-piece refractor system

uses the combination of

diusing optical lm and

precisely extruded prisms to

eciently diuse light.

Reector includes micro-fac-

ets that echo the frequency

of the prisms in the refractor,

providing a quiet appearance

in the ceiling.

Lamp accessed by squeezing

refractor to release from

retention tabs.

Optics

Delivers volumetric lighting

by lling the entire volume of

space with light, delivering

the ideal amount to walls,

cubicles, work surfaces and

people. Luminous character-

istics are carefully managed

at high angles to deliver just

enough intensity to provide

the volumetric eect.

Electrical

Ballast disconnect provided

standard where required

to comply with U.S. and

Canadian electrical codes.

A wide variety of ballast

congurations including set

light output or step-level

dimming. Step-dimming op-

tions allow the system to be

switched to 50% power for

compliance with common en-

ergy codes while illuminating

both lamps. Highly ecient

programmed start electronic

ballast, Class P, thermally

protected, resetting, HPF,

non-PCB, UL Listed and CSA

certied, sound rated A.

Premier F28T5 lamp with en-

hanced phosphors and 85 CRI.

Ballast/lamp ecacy of 28T5

is 100+ LPW. Side mount bal-

last tray accessed by removing

adjacent ceiling tile.
