How do we reduce the costs of lighting installation?

We established HARDO as an independent company based on the over 20 years of experience of the WOLFF GROUP in providing and designing lighting fixtures for explosion hazard zones, to address all the main market challenges that ultimately raise the purchase and installation costs of lighting installations for investors.

From the beginning of constructing OptiLine fixtures, we focused on eliminating all the issues that previously arose during the design and installation of lighting fixtures. Solutions to two of these problems can be seen in the animations below.

No junction boxes, fewer cables

We enabled through-wiring of fixtures. You no longer have to buy expensive Ex junction boxes. You’ll also use fewer cables and cable trays.

Directional lenses, with which you can change the light direction without changing the fixture

Thanks to directional lenses, we eliminated many additional costs that appeared during installation and later operation. Previously, when you needed to illuminate critical areas such as switches, valves, extinguishers, etc., you often had to figure out the right way to mount the lamp. So you incurred the cost of additional, non-standard materials and the cost of additional labor for the installer. Thanks to directional lenses, you simply change the direction of light without these works and materials. Simple, right? And when you change the position of these points during operation, you only change the lenses, not the whole lamps.

Wide range of luminous power and impressive efficiency of ATEX OptiLine fixtures

Ex ATEX emergency lighting fixtures powered by a central battery

The ATEX OptiLine lighting fixture is characterized by extraordinary versatility and high efficiency, offering a wide range of luminous power. Available in two lengths – 600 mm and 1270 mm, with three power variants for each and three types of diffusers to choose from, it creates a total of 18 configurations of basic fixtures.

  • basic light streams from 2931 lm to 10342 lm,
  • emergency light streams from 1400 lm to 5150 lm,
  • high efficiency of complete fixtures from 137 lm/W to 175 lm/W guarantees energy efficiency and reduction of operational costs.

Not so obvious, but changing reality competitive advantages

Fixtures in versions: transparent, frosted, and opal

The versatility of the OptiLine fixture is expressed not only in the possibility of using it as both primary and emergency lighting. Versatility additionally means the option to choose from three types of diffusers, each intended for a different type of application, taking into account the lighting needs of explosion hazard zones inside and outside industrial and storage buildings.

OptiLine basic lighting fixtures ATEX

Transparent diffuser

Frosted diffuser

The frosted diffuser provides the ideal balance between the need for a high light stream and eliminating the risk of glare.

  • Light streams up to 9981 lm without glare
  • Gently diffused light

Opal diffuser

The opal diffuser is an excellent choice for interiors where the priority is diffused, comfortable light.

  • Light streams up to 8747 lm without glare
  • Perfect for interiors

Innovative solution with glands and power connectors

The Ex OptiLine fixture stands out for its innovative cabling. It includes two easily accessible power connectors located on both ends, and its body can accommodate up to four M20 or M25 cable glands. Such a design allows for significant cost reductions by eliminating expensive Ex junction boxes and reducing the use of cables and cable trays. Unlike many fixtures that are limited to a single gland, OptiLine enables simpler and cheaper mounting solutions, especially in situations requiring the installation of many fixtures.

Want to use flame-retardant cables or those with larger cross-sections of wires? No problem!

The OptiLine fixture allows for the use of M25 cable glands. This solution allows for the use of cables with larger cross-sections, which is extremely important in situations where high temperature resistance is required, as in emergency lighting. A larger diameter of glands also provides greater freedom in choosing cable manufacturers and allows for the use of thicker and safer wires, which is key in limiting voltage drops.

From an installer’s perspective: safe and quick installation

Ex ATEX emergency lighting fixtures powered by a central battery

This modern lighting fixture offers unique solutions for quick and safe installation without the risk of losing loose parts. The spacious interior design facilitates power connection, and hand-unscrewable captive screws provide easy access to electronics. Hinges in the diffuser and the plate with the LED module ensure that they stay in place during work, eliminating the risk of falling. Additionally, all elements are solidly connected, increasing the durability and safety of the product.
