until recently, small aperture 2" LED products were only suitable for niche or accent
lighting. With Prescolite’s revolutionary 2" LED downlights, it’s now possible to
experience a new dimension in lighting design for commercial applications.
With custom optics designed around the precision Xicato brand light
engine, D2LED and A2LED offers the opportunity to create clean ceilings
with minimal obtrusiveness. The downlight provides general, workable
light output – including track and accent lighting – in new construction
and retrofit applications, such as:

With Prescolite’s 2" LED lighting, lighting designers and architects can have it all – minimal aperture size, efficiency
and premium optics – when lighting highly aesthetic environments.

When viewing a downlight your eye
does not perceive the size of the
aperture relative to the diameter, but
rather, to the area of the opening! So
the D2LED appears to be 1/4 the size of
a typical 4" downlight.

Prescolite’s heat sink features a state-of-the-art design for optimal
thermal management. The design provides consistent unrestricted
heat flow from the source to the air. This ensures maximum life and
consistent color over the fixture’s lifespan.

D2LED’s unique design doesn’t require a frame to be
installed into a ceiling – in most applications. To support
the downlight in weak ceilings, such as tiles, Prescolite
offers the D2FRM plaster frame option.
A special option is available for applications
that require an IC Box – such as high-end
residential settings. The D2ICAT IC-rated,
and airtight box is an ideal for installing the
downlight into an insulated ceiling.*

d2Led wALL wAsH: A POweRFuL cOmBINATION
OF uNIFORmITY ANd cONTROL
12
The D2LED wall wash brings all the superior control of the D2LED and
combines it with a revolutionary approach to wall washing.
This unique approach to optical design for wall washing, along with the
innovative mounting method, raises the bar on wall wash performance.
D2LED wall wash yields distributions that outperform most larger aperture
specification grade downlights with traditional sources.
LIght-PIPE tEchnoLogy
Prescolite’s patent-pending light-pipe
technology harnesses the light from the Xicato
module and transfers it down into the downlight
with minimal degradation, maintaining a clean,
highly controlled wall wash.
The cut end of the light-pipe has an exclusive
lenticular tooled pattern to direct each individual
light ray for perfect optical control.
smALL APErturE
The D2LED wall wash is
configured in the same way
as the standard D2LED with
its signature 2-inch nominal
aperture, allowing for a clean
ceiling and unobtrusive
appearance.
WWW.PRESCOLITE.COM
unIformIty
The wall wash configuration of
the D2LED maintains the same
even light distribution and smooth
beam edge that the standard
version offers.
cLosE to cEILIng
The D2LED wall wash illuminates
the wall from ceiling to floor, with
a quality of light not seen before
in this configuration, including
a smooth transition close to the
ceiling plane.

oom sIDE
contrIButIon
Not only does the D2LED wall wash
perform superior wall washing, but it
also incorporates the same superior
downlighting to the room-side of
the fixture, with no room-side glare,
utilizing the same VirtualSource
appearance as the standard D2LED.

In four EAsy stEPs, you cAn InstALL D2LED AnD A2LED In your nExt LIghtIng DEsIgn.
Before the ceiling is finished, run wiring to the approximate location
where the D2LED or A2LED will be installed.
stEP 1:
mAkE cEILIng cutout
Use a 2 7/8" hole saw and
pilot drill to cut an opening
for the D2LED or A2LED
downlight. Because of the
small reflector flange of the
fixture, the accuracy of this
hole is critical. Even a 3" hole
saw may leave a ceiling cut
out too large to be completely
hidden after installation.
WWW.PRESCOLITE.COM
stEP 2:
run WIrEs to J-tuBE
Pull the pre-existing wiring
below the ceiling and connect
to the J-tube assembly through
the 1/2" knockout. A 3/8" flex
conduit duplex connector may
be used to easily daisy chain
fixtures together or for end-ofrun
applications a standard 1/2"
connector can be used.
Because both the D2LED and
A2LED feature a 0-10 volt
dimming capability, be sure to
include any low voltage wire
connections in this step. When
wiring for dimming, the low
voltage wiring installs through
the adjoining 1/2" knockout. A
second 3/8" flex conduit duplex
connector may be used in this
knockout where applicable.
stEP 3:
sLIDE/snAP J-tuBE cLosED
Simply slide the J-tube closed until
it locks into place with the springs
on opposite ends of the assembly
to complete the third step.

stEP 4:
InstALL fIxturE Into cEILIng rEmovAL for sErvIcIng
When installing the A2LED, be
sure to adjust the vertical angle
at this stage.
Feed the J-tube assembly through
ceiling cutout. The J-tube assembly
has been designed and CSA
approved to conveniently lay on top
of the ceiling material.
Squeeze the retention springs,
insert the light engine assembly
into the cut out, and push until the
springs pop out above the ceiling,
locking the fixture into place.
Once installed, being careful not to
leave finger prints on the reflector,
gently twist clockwise slightly to
secure firmly against ceiling.
While the D2LED and A2LED are
designed with a life expectancy
of over 50,000 hours, there may
be times when you may need
to access the fixture or J-tube
assembly. For this reason, the
fixtures have been designed to
come out of the ceiling as easy as
they went in.
Twist the reflector slightly
counter-clockwise while applying
slight downward pressure. Then,
once the springs are accessible,
squeeze them together and
remove the fixture from ceiling.
For emergency egress lighting,
D2LED and A2LED are tested and
compatible with Dual-Lite 100VA
and 250VA LiteGear ® inverters.
