Grah Lighting was established as a division for the LED street and industrial light program of the company SGA (Schefenacker Grah Automotive – SG Automotive d.o.o.), which is a trusted partner and supplier for leading car manufacturers such as Mercedes Benz, BMW, Audi, Porsche, Ferrari, Jaguar, Maserati, Maybach, Rolls Royce, VW, Ford, GM, Nissan, Volvo, Toyota, Alfa Romeo, Cadillac, Chrysler, Fiat, Lancia, Opel, Renault, Rover and SAAB.
Since 2009, Grah Lighting is a subsidiary company of SG Automotive and is fully specialized in energy efficient LED street lighting, industrial and office lighting. Grah Lighting aims to be the global leader in ultra energy efficient LED lighting with the ability to satisfy the needs of the most demanding customers, requiring top quality products and reliable solutions.
Our specially developed, QUADRUM optics™ consists of thin prismatic nano treated lenses made from optically optimized polymers, which contributes to incredibly low losses within primary optical part.
All lighting spots together form unique MATRIX 3D LIGHT™, which increases the utilization rate of light on the surface, reduces glaring and allows for the best possible light uniformity.
Due to our specific needs, we have gone one step further and developed customized I-NFINITY driver™ (100-250 V), which self-adapts to voltage fluctuations, accepts various kinds of regulation (e.g., dimming reduction) and can withstand a direct current strike according to ENEC.
With the help of the most modern computer software for calculation and simulation of thermic transfer, we researched and analyzed the temperature change direction around a particular location of the unit. Combining these findings, advanced materials and state of the art patented housing we achieved one of the most optimized dimensional air and temperature flows that produces the best possible cooling effect – COOLVERT™ solution.
Through our special treatment method, we customize SAMSUNG LEDs and merge them into our specially engineered patented LED modules – LED GENION bars™, where every single LED position is precisely calculated and positioned under certain angles.
According to the latest bionic studies, the housing shape was inspired by imitating living systems from nature and adapting observed living functions to practical purposes. The result is a modern fully sealed inflow resistant AEROCOMPACT casing™.
Beside the unique innovative shape of the housing and it’s technical perfection we also assured extreme durability. The housing of our lights is made of super light aluminium alloy, treated with ULTRA COATING™ – special multi layer galvanic protection and final special color finish from highly durable polymers.
The robust housing of Aerolite LSL and ECO® luminaire is resistant against external mechanical impacts (shock, vibration, etc., and is protected against energy at the impact of 5 Joule) according to acquired rating IK10. With high quality insulation, specially protected electronics and fully sealed housing, the luminaire ingress protection rate is IP66.
LED lights are readily available for seamless upgrade of the system for different multifunction options (light management via online-integrated network, wireless internet connection- WIFI, security cameras, other security applications, video control, remote control, speed sensors, light sensors, emergency switches, etc.).
We are constantly improving work processes and modernizing the production equipment (3D robotic technology for applying gasket, orthopedical adapted working places, etc.). We have developed our own manufacturing procedures at different stages of the production line in order to optimize time and processes.
