Specifications
Optical System
The optical system is comprised of arrays of LEDs edge lighting a low profile
light guide panel. The micro structured surface of the light guide panel
optimizes the light extraction creating a homogeneously luminous appearance.
Light is then controlled by MesoOptics film suppressing the high-angle light
creating an ultra low-glare bat-wing distribution.
Finish
Housing and Frame painted, high quality, powder coated matte white only.
Housing
Sides and center spine: precision aluminum extrusion; end caps, back housing
and driver cover: die-formed, 20 gauge cold-rolled steel, pre and post
painted. Available in white. Multiple wire entrances are available (top or
side) to allow continuous row mounting of fixtures.
Weight
Maximum 28lbs (2×4); 21lbs (1×4); 15lbs (2×2).
Electrical
Factory pre-wired with driver safety disconnect.
Mounting
Fixtures are factory pre-wired and tested for all circuits and emergency
battery packs. Compatible with 15/16″ lay-in acoustical ceilings using exposed
grid suspension (NEMA type G). For 9/16″ slot T-grid ceilings, fixture will
sit 5/16″ above bottom of Tee. Optional drywall kit trim mount can be fastened
to a wood frame or with hangar wire. Continuous row mounting not available
with drywall kit trim mounts.
Standard Driver
Advance Xitanium 0-10V, 1% dimming.
Advance Xitanium Sensor Ready (SR), 5% dimming.
PoE Lighting Controller (for PoE tunable white).
Lutron EcoSystem LDE1, 1% dimming with Soft-on, Fade-to-Black.
Class 2 rated output.
Consult Ledalite for other available drivers.
Standard Battery Packs
Bodine Battery Pack, 90 min, 10W, Class 2 rated output.
Lumen output = 10W x luminaire efficacy x 1.1. Typical output 1100lm.
PoE Battery Pack, 90 min, 6W, Class2 rated output.
Lumen output = 6W x luminaire efficacy. Typical output 650lm.
Lumen Maintenance
LEDs have been tested by the manufacturer in accordance with IESNA LM-80-08.
At an ambient temperature of 25°C, the LED lumen maintenance expectation
according to IES TM-21-11:
L90 (10k) >60,000 hrs (Reported methodology)
L80 (10k) 125,000 hrs (Projected methodology)
Source Color
LEDs rated for color rendering of:
CRI >80 & R9 >0
CRI >90 & R9>50
Fixture to fixture color accuracy within:
2 SDCM for Static White luminaires
3 SDCM for Tunable White luminaires
Wiring
Optional flex whips are supplied in 6′ lengths.
Approvals
Certified to UL, CSA, and IES standards. City of Chicago Approved CCEA
(housing option C).
Quick Ship
Available for most non-connected configurations upon request. More information
available at: www.signify.com/en-
us/brands/ledalite/quickship
Warranty
Five-year luminaire limited warranty including LED boards and driver.
www.signify.com/warranties
Environment
Rated for dry & damp locations in operating ambient temperatures of 0-25°C
(32-77°F). Many luminaire components, such as reflectors, refractors, lenses,
and LEDs are made from various types of plastics which can be adversely
affected by airborne contaminants. If sulfur based chemicals, petroleum based
products, cleaning solutions, or other contaminants are expected in the
intended area of use, consult factory for compatibility. Damage caused by
sulfur, chlorine, petroleum based solution or other contaminants are not
covered under warranty.
