Technical specification

- intended mainly for interiors, e.g. lighting of cabinets, stairs, display windows etc.
With their small size, the lighting fixtures can be concealed in the walls of the furniture with small cross-sections
- in the sealed version, it can be used outdoors, for example on the facade of buildings,
in the elements of garden architecture, in fencing elements, etc.


- can be mounted with appropriately selected fixing glues, professional double-sided adhesive tapes, metal and plastic mounting brackets, as well as mounting brackets with angle adjustment, and by means of a mounting spring

Additional information

- suitable for bending in the plane adjacent to the LED strip
- can be equipped with transparent and frosted covers (diffusers), aluminum-colored plastic end caps, metalized and conductive end caps
- must not be used for diodes emitting high temperatures
- lighting or illumination of certain areas (stream of light may vary depending on the power of applied LEDs)
- illumination of hardly accessible areas – shaded spots
- spece for LED strip: 0.44" / 11.2 mm


Extrusion bending


Minimum internal radius

Minimum external radius

150 mm / 5.9"

150 mm / 5.9"


- Minimum radius – bending radius which when exceeded causes destruction
  (deformation, bending or lack of compatibility with other accessories, e.g. covers, end caps, etc.) of the profile.

- Internal radius – refers to the extrusion bent so that the cover is facing the inside of the arch.

- External radius - refers to the extrusion bent so that the cover is facing the outside of the arch.

- Irregular curves are possible after consultation and individual quotation.

- When bending anodized extrusions, one should be aware of cracking of the anode coating (which may be more or less visible depending on the radius).


Possibility of making a linear fixture with IP67 protection, which means the fixture is dustproof and waterproof.
Achieving IP67 is possible with the following covers: LIGER-22, MUN-22 and HS-22.

Turn off LED lights during peak day light hours in outdoor applications to avoid excessive heat buildup which will result in diminished LED life.
