Moisture, UV radiation and temperature amplitudes of over 60 degrees in the span of one year – this is the work environment of every facade lighting fixture in our latitudes. The Philips Topiary series is designed as an answer to these aggressive factors, relying on physical span for better heat management and high class of protection IP44. How do these specifics turn into actual value for the investor? We contacted specialists from Filkab – a company, whose name is synonymous with engineering competency and reliability in distributing electro materials.

"It is important for us to offer solutions that do not generate complaints, and Topiary is exactly such a solution. The combination of anti-corrosion materials and the ability to integrate the most modern LED sources into a traditional lamp holder gives designers freedom that is missing with encapsulated modules. This is a product for people who plan for ten years ahead, not for the next season," Filkab told BalkanEngineer.com.

At the base of the Philips Topiary model stands an aluminum alloy obtained by high-pressure casting. Unlike extruded profiles or bent sheet metal, the cast body is monolithic, which eliminates weak spots and welds where corrosion usually begins.

Besides mechanical durability, an interesting element is the surface work, based on strict Signify production protocols (the corporate structure of Philips). Before the final powder coating, the aluminum castings undergo a chemical preparation stage – an industry standard to ensure corrosion resistance of C3 or higher. This ensures that even if the paint is mechanically damaged, the aluminum underneath will not develop progressive oxidation.

Filkab specialists emphasize that it is this multi-layered approach to the product finish that allows Philips to maintain a high aesthetic standard even in coastal areas or industrial urban environments.
