doublepower!! RAY

doublepower!! RAY luminaries provide exceptional and efficient illumination of high rack corridors floor and high rack shelves at the same time.



Unique features

  • Exceptional thermal management of the luminaire ensures extremely efficient heat dissipation
  • Operating temperatures range –40 °C ~ +65 °C (TaMAX version)
  • Special optic system for consistent and highly efficient illumination of both shelf aisles and the goods in shelfs
  • Variable combination of various optics and lighting characteristics in one luminaire
  • Long-term high efficiency, very slow decrease of luminous flux over time
  • Modular design – optical part and part with electronics are separated
  • Highly variable mounting system for most of the common mounting and hanging systems
  • IP54 protection
  • Warranty up to 10 years, luminaire’s lifetime including electronics min. 100,000 hours

Unique way of illuminating high rack aisles

With the doublepower!! RAY luminaire we achieved incomparable lighting parameters, ideal for installation in shelf aisles and especially in high mounting heights. There are two types of optics installed in the luminaire. Due to their different light distribution characteristics, the luminare is able to efficiently and evenly illuminate not only the aisle pathway, but also the vertical wall shelving.

Thus, doublepower!! RAY luminaires offer unprecedented illuminating qualities for high rack logistic centers and exceptional energy savings.

Thermal management, protection rating

termo-rayAs well as in case of doublepower!! TREE, unique design features are applied in case of doublepower!! RAY. One of them is special aluminum body design with exceptional heat management, or the LED chip supply current solution.

Usually there are not so harsh conditions and high ambient temperatures in logistic halls as they can be in some production facilities. The minimal difference between ambient temperature and the temperature inside the luminaire is still extremely important in logistics – the operating conditions of LED chips and electronics are very comfortable. Thus exceptional life-time and long term sustainability of lighting conditions are ensured.

From many experiences from logistical installations we know that even in a common logistic operations luminaries without sufficient cover protection are subject to dust and impurities.

We know from experience that even in normal logistics operations, open luminaires are subject to dust and impurities. This reduces their efficiency and increases the likelihood of defects. Therefore, we provide doublepower!! RAY luminaires with IP54 protection.

Glare factor

In order to ensure low glare level (UGR), in doublepower!! RAY luminaires LED modules are embedded into the luminaire’s body. There are a number of low-wattage LED chips installed in doublepower!! RAY, and each LED chip is covered by its own optic. More than that, there is sufficient space between optics and LED chips. The light is not radiated from a very small space in a too big intensity, which further contributes to low glare factor.
