ven when you have selected the most energy
efficient luminaire/ballast/lamp combination for
your space, additional energy savings can be
made by utilizing natural daylight through use of
controls. In the past, many have felt "Daylighting"
was too complicated because of the wiring
required for the interface of the fixtures to the
control sensors, the adjustability of the sensors
and the inflexibility if you relocated furniture or it
did not quite work to your satisfaction.

ULM-EZR Module blends in with the ceiling system.

NOW, LIGHTOLIER makes DAYLIGHTING as EASY as 1-2-3

Install a ULM-EZR module in the ceiling, positioning it 6 to 10 feet from windows
and over a work surface (it must be within 10 ft of a luminaire).
Using the low voltage plug-in 12' long CAT5 cables provided with the
luminaires*, connect the luminaire and ULM-EZR module.
An additional CAT5 cable will be provided with each luminaire* to plug in
additional luminaires* as in a daisy chain. Up to 20 luminaires* can be
connected to a single ULM-EZR module.
ULM-EZR modules can be moved or added at any time merely by plugging or
unplugging the CAT5 cables.
Both ULM-EZR modules and fixtures have proprietary RJ45 dual receptacles for
the CAT5 cable with RJ45 plugs.

When there is no daylight, place a lightmeter on the work surface and take a

footcandle reading.
Adjust to desired footcandle level by rotating the sensor in the face of the
ULM-EZR Module.

To get MORE light on desk from the
luminaire, close aperture by rotating
it counter-clockwise.
The lamps will get brighter.

ULM-EZR module sensor placement guidelines:
Before adjusting sensor settings, check to make sure they have
been installed in accordance with the following guidelines:
Sensor SHOULD be located

• Between 6-10’ away from window

• Over work surfaces
Sensor should NOT be located

• Over very dark surfaces (e.g. dark carpet or furniture)

• Over highly reflective surfaces (e.g. polished floors or tables)

• Outside the daylit zone (typically beyond 15’ from window)

To get LESS light on desk from
the luminaire, open aperture
by rotating it clockwise.
The lamps will dim down.

The sensors are factory pre-calibrated to 45fc on the horizontal,
assuming standard reflectances (80/50/20), ceiling heights
(8-10’) and work surfaces (2.5’).
To return to the default setting, rotate the aperture until it ‘clicks’
back into place at the mid-point.

Ordering Guide:
