II. Product Scope:

Mainly used for class II (other than coal mines of explosive gases or steam), II a, II b and II c-level, temperature class for T1~T6 explosive atmosphere zone 2 hazardous areas and T1~T6 temperature group of combustible dust and air to form a mixture of environment zone 21 and zone 22 places. As use of the operations, activities, and other indoor and outdoor lighting.

III. Core Values:

  • Energy Conservation: Reduce lighting energy consumption, achieve energy-efficiency targets, and reduce operating costs.
    • High Quality LED light sources, light efficiency is greater than 1001m/W than fluorescent light over 50%
    • Software simulation design, special transparent material with light transparency, high lighting efficiency.
  • High lighting comfort: no glare, no flicker, bright and comfortable lighting environment, reduce misoperation and the visual fatigue, improve the efficiency and quality of
    • Special light translucent material, uniform illumination and high lighting glare.
    • Environmental health, mercury-free LED light source elements, no Flash.
  • High reliability reduce the impact of lamps of normal  production after a failure, reduce maintenance costs.
    • High-quality LED, Good heat dissipation structure LED only 10 degrees of temperature rise, life up to 100,000 hours to achieve maintenance-free
    • Full bridge uses the latest technology, plastic technology, wide input voltage of high reliability electronic drive.
  • From structural design to meet water requirements, product shell protection grade IP66, can be used indoor and outdoor places and reliable;
  • Main shell for aluminum extrusion, Anodic oxidation treatment on the outer surface, shell shock-resistant high strength, corrosion-resistant level at WF2, can be used in corrosive environment medium-and long-term reliable operation;
  • High Quality, enhance brand image
    • Streamlined appearance shape-designing, structural design of high quality aluminum alloy shell material, integration.
  • Maintenance-free low-carbon, LED lighting

For all-solid luminous, shock-resistant, impact resistant unbreakable, waste recycling no pollution. Of course, saving energy is the main reason we consider using an LED light source, perhaps LED light source is more expensive than traditional light sources, but about a year back light source of energy-saving investments, resulting in net income from 4-9 several times a year in energy conservation.
