| CHARACTERISTICS OF SAMMODE TUBULAR LIGHT FITTINGS |

|
| SAMMODE IMPERVIOUSNESS |
 |
 |
Two fundamental principles are at the basis of the
imperviousness of our tubular light fittings. They
enable them to be really hermetic, not only when
immersed in calm water (IP68) but also to high
pressure jets (IP66).
1. The longer the seal, the higher the risk
of ingress.
On our tubular units imperviousness is executed
at the end of the tube, thus enabling
the length of the seal to be reduced as
much as possible. |
|
|
| |
|
2. The force of application of the seal must
be homogeneous and constant over
time on the whole of the bearing surface.
The closing of the unit by a central stainless
steel screw applies a homogeneous force at all
points of the bearing surface of the seal. The
elastic deformation of the stainless steel flange
takes up the dilation and mechanical constraints
exerted on the casing of the light fitting
throughout its life. |

RESISTANCE
TO THE ENVIRONMENT |
|
The combined use of anti-UV treated polycarbonate and stainless steel, together with exceptional imperviousness, enables our lighting units to be used in the worst conditions of humidity, dust and dirt, both indoors and outdoors.
The shape of the tubular casing without sharp
edges enables it to be cleaned easily, and its
mechanical strength allows this to be done by high
pressure jets (of the KARCHER type).
In surroundings which are very sensitive to certain
chemical agents or subject to extreme soiling, we
recommend the use of borosilicate glass casings
because of their resistance to chemical attack and
ease of cleaning. |
|
|
| |
|
| For corrosive and saline surroundings we advise you to use marine quality 316L stainless steel, which is available on request for all our product ranges. |
|

|
| MECHANICAL STRENGTH |
 |
|
The use of tubular casings enables the mechanical
strength of the basic materials used to be increased
(polycarbonate with high resistance to shocks and
borosilicate glass):
• Improved distribution of the mechanical constraints.
• Rigidity under all conditions.
• Absence of a longitudinal seal plane, maintaining
the homogeneity of the material and contributing
to increased resistance to shock.
|
|
|
| |
|
The combination of these factors enable our light fittings
to achieve exceptional resistance to shock
(IK10) for the polycarbonate versions and a resistance
to shock for the units with a borosilicate glass
casing which is higher than that of units with a classic
acrylic bowl (IK07). |

QUALITY |
|
Our light fittings are exclusively manufactured from high quality materials, stainless steel, crystal quality anti-UV treated polycarbonate with high shock resistance, borosilicate glass, etc.
Our gear trays are in sheet steel protected by polyester
powder paint baked in an oven at 200°C, and they include electric and electronic components which are selected in our laboratories for their capacity to satisfy the most rigorous specifications.
Our optics in polished aluminium are developed by
our photometric design office. They enable our engineers
to find the best compromise between casing
characteristics and luminous efficiency.
|
|
|
| |
|
| Lastly, every light fitting is assembled with great care in our factory at Châtillon sur Saône (88) and is checked and tested individually when they come off the production line. Each unit has its own serial number, which enables complete traceability of the light fitting and its components. |
