Introduction
The range of floodlighting products offers great
possibilities. The different colors and beam
angles make that we can create all kind of lighting effects, from very soft to colorful accents. The
effects can be static or dynamic and fully controllable.
This application guide shows some examples and
according rules of thumb.
The rules of thumb are based on real tests.
These tests have been carried out with the
eW 4000K version. This version is also used for all
calculations and visualizations.

How to use this guide
Link with the architectural scale
In the chapters of this guide, you will find different lighting
applications covered by several product ranges.
The table on the right shows on which architectural scale we
choose to illustrate each product range. Of course, these values give only an indication and can be adapted to your own
preference.
Range

Very small (0-3m)
Burst

Blast
Medium (4-8m)
Reach
Large (8m - 100m)
Working with white and colored light
The calculations and visualizations in this guide are based
on eW 4000K. For other versions, eW 2700K, iW, Color and
eColor the light output (flux) is different and therefore the
results too. The flux table on page 10-11 shows the luminous
flux in lumen.
The values for colored light are low compared to white.
This leads to wrong conclusions. The human eye is much
more sensitive to colored light.

The figure on the right illustrates the percentages of colored
light, needed for the same perception of brightness
compared to white light.
(color contrast study, LiAS 2009).
Methodology
To create this guide, all lighting applications have been
tested at night with the products. The rules of thumb are
based on these visual tests. Then, the lighting levels have
been calculated in a lighting software, Calculux.
3D software
For the 3D visualizations, 3D Studio Max is used. This is a
modelling and rendering software. In the guide, renderings
are used to show the lighting effects. Additional false colors
give an idea of the light levels.
The rendered images have been validated by real tests.

Visual beam angle (VBA)

E (lux)
Light patch at a given distance
The typical definition of beam spread refers to the halfintensity, indicated in intensity diagrams (b). This means the
spread of the beam within which the intensity is more than
50% of the maximum value. The related beam width does
not correspond to the size of the lit area on the surface but
merely to the theoretical angle of the beam.

Visual beam angle (VBA)
Lighting a sculpture requires to know the size of the light
patch that will be applied on it. This way, the light is focused
on the object to be lit. The width of this light patch can be
deducted from the visual beam angle (page 5).

A narrow beam placed close by produces
a strong accent. The illuminated area
depends on the visual beam angle and

Introduction
The range of floodlighting products offers great
possibilities. The different colors and beam
angles make that we can create all kind of lighting effects, from very soft to colorful accents. The
effects can be static or dynamic and fully controllable.
This application guide shows some examples and
according rules of thumb.
The rules of thumb are based on real tests.
These tests have been carried out with the
eW 4000K version. This version is also used for all
calculations and visualizations.

How to use this guide
Link with the architectural scale
In the chapters of this guide, you will find different lighting
applications covered by several product ranges.
The table on the right shows on which architectural scale we
choose to illustrate each product range. Of course, these values give only an indication and can be adapted to your own
preference.

Working with white and colored light
The calculations and visualizations in this guide are based
on eW 4000K. For other versions, eW 2700K, iW, Color and
eColor the light output (flux) is different and therefore the
results too. The flux table on page 10-11 shows the luminous
flux in lumen.
The values for colored light are low compared to white.
This leads to wrong conclusions. The human eye is much
more sensitive to colored light.

The figure on the right illustrates the percentages of colored
light, needed for the same perception of brightness
compared to white light.
(color contrast study, LiAS 2009).
Methodology
To create this guide, all lighting applications have been
tested at night with the products. The rules of thumb are
based on these visual tests. Then, the lighting levels have
been calculated in a lighting software, Calculux.
3D software
For the 3D visualizations, 3D Studio Max is used. This is a
modelling and rendering software. In the guide, renderings
are used to show the lighting effects. Additional false colors
give an idea of the light levels.
The rendered images have been validated by real tests.

Visual beam angle (VBA)

E (lux)
Light patch at a given distance
The typical definition of beam spread refers to the halfintensity, indicated in intensity diagrams (b). This means the
spread of the beam within which the intensity is more than
50% of the maximum value. The related beam width does
not correspond to the size of the lit area on the surface but
merely to the theoretical angle of the beam.

3. Sculptures
Visual beam angle (VBA)
Lighting a sculpture requires to know the size of the light
patch that will be applied on it. This way, the light is focused
on the object to be lit. The width of this light patch can be
deducted from the visual beam angle (page 5).

Accent lighting
14m
The Reach is well adapted to large size
sculptures. The 13° lens produces a strong
accent. Lighting from the bottom to the
top creates a very dramatic effect.

A wide beam will produce a softer effect
on the sculpture. Depending on the
visual beam angle, it will cover almost
all the statue. The object seems uniform
and flatter than when illuminated with a
narrow beam.

A combination of beams is used to
balance the scene:
- the 13° beam highlights the upper part
- the 40° beam reveals the lower part and
avoids the statue to "float". It the brings

Burst Compact
From outside
Lighting low vegetation from outside with
a wide beam creates a soft and uniform
effect. It reveals the outer bushes and
flowers but flattens the image.

From inside
Lighting placed inside the vegetation
creates a silhoutte effect, a glow. It shows
the density of the foliage. It is more
difficult to read the whole image because
only parts are highlighted.

Accent lighting on trunk
A narrow beam placed close to the trunk
produces a strong accent. The rest of the
tree stays in the dark. The image is quite
dramatic. Main focus is on the trunk.

Glow of light
Two or three luminaires (depending on
the size of the tree) are placed under the
foliage and aimed upward.
The leaves make the inside of the tree
glow, revealing the volume of the crown.
This positioning avoids a floating effect
because the trunk is softly lit.

A combination of effects can be used
to prevent the crown to float. More
interesting effects can be achieved by
using different color temperature.

Reach
Glow of light
The light will make the tree glow from
inside. A more narrow optic (5° to 13°)
will focus the light either on a part of the
foliage or on the trunk. A wider optic (40°)
will spread light.
This effect is less interesting for trees with
dense foliage.

Soft wash of ligth
Floodlighting trees with dense foliage is
best from the front. This gives a soft and

tree.

Combination of lenses
One Reach is placed in the center of a
group of trees with a combination of

the trunks and underside of the crowns.
- 23° lens illuminates the foliage from
inside reaching almost to the top.
