One-row plastic industrial LED light fitting intended for extreme temperatures -40°C to +65°C, with diffuser made of translucent polycarbonate.

The light fitting is suitable for indoor and outdoor with roof with extreme ambient temperatures from  (-40 °C to +65 °C). The fixture is designed especially for refrigeration, cold stores, bakeries, heating plants, metallurgical lines, glass factories and other premises without the danger of explosion of gases, dusts and flammable vapors.

The light fitting is resistant to dust, moisture and spouting water. The body and the diffuser made of polycarbonate (PC) have the increased resistance against deformation and impact.

(It is necessary to consider exhalation in the air which can reduce the usability of the plastic at installations in an aggressive environment).



  • Light fitting protection: IP66
