A2. Usage instructions
- The Workbench Lighting product range
(Spiral IL-5400-v.2.0) has been developed
for macroscopic inspection. The Spiral
lamp has been designed to be used in
workshops, in industrial environments
or in R&D laboratories.
- The product generates visible light
of high intensity. When inspecting
components consisting of materials that
absorb visible light, it is recommended to adjust the distance between the light
ring and the observed sample in order to avoid thermal degradation of the
lighted object.

B2. Inspection angles
B2.2. Inspection through the light
source axis
The lamp is positioned in the user
observation axis. The sample is
inspected through the hollowed
lamp head. This inspection method
is particularly useful for very precise
control and when the magnifying lens
or the light box are mounted on the
lamp.
The observed sample should be
placed 15 cm away from the lamp
head to obtain 2’500 lux illumination.
Thanks to its hinge, the lamp is
reclining in a range from -20° to
40° allowing to observe samples at
dierent angles.
The IL-5400-v.2.0 lamp has been designed to facilitate inspection under dierent
lighting angles. Two positions can be chosen by the operator for ergonomic use.
B2.1. Traditional inspection
The lamp is positioned outside of the
user observation eld.
With the elbows rested on the
workbench, the user maintains a
comfortable and straight sitting
posture.
The observed sample should be
placed 15 cm away from the lamp
head to obtain 2’500 lux illumination.
In this conguration, a watchmaker
loupe can be used close to the lamp
head which does not dissipate heat.

B3. Accessories
The following optional accessories can be ordered to enhance the usage of the
product.
-Power supply 12V (AC-PS-12-EU)
Available with European (EU), Japanese (JP) or
British (UK) interfaces, it supplies the lamp with
power via the electrical network.
-Magnifying lens (AC-MG-2XR-I)
Renders a detailed view of the sample with a
x2 enlargement (dioptre 4). Thanks to its large
dimensions (130 x 100 [mm]), it allows a magnied
observation with both eyes.
-Light box (AC-LB-180-EG-I)
The light box extends the rim of the light ring.
It isolates the inspection area from stray light
and enhances lighting uniformity in a three
dimensional space.

B4. Assembly of accessories
When installing accessories, do not over-tighten the screws as this may damage the
screw thread or distort the lamp.
Regarding the connection of the system to the electrical network, please refer to
B.1. “Setup”.

Assembly of accessories (cont.)
B4.1. Attaching the lamp to the base unit
Make sure that the screw on the rear of the base unit is unscrewed, allowing enough
space for the lamp rod to be inserted. Insert the lamp rod into the base. Tighten the
screw at the rear of the base unit until you feel a light pressure and that the lamp is
securely inserted but can still be rotated.
B4.2. Attaching the magnifying lens to the light ring
Insert the lens on top of the light ring with the lateral pins face down. The lens can
be placed to the left, in the center or to the right of the head of the light ring. Then,
tighten the security screw (A) positioned on the lens side.
B4.3. Attaching the light box to the light ring
Place the light box below the light ring and tighten the 2 lateral screws situated at
both ends of the light ring (B).
