Illuminated advertising that even survives in the desert

When the sun shines mercilessly from above, thermometers in Dubai can climb to 45 degrees Celsius. PLEXIGLAS® protects the black lettering of the popular Dubai Mall from high levels of UV radiation – and illuminates the lettering in an even white at night.

More than 80 million visitors flock to the Dubai Mall annually, and with over 1,300 shops, the Mall is among the world’s largest shopping centers. Equally impressive is the huge “The Dubai Mall” lettering on the façade which points the way for visitors to the Mall from a long way off – by day and by night.

Visibility through contrast

During the day in the desert metropolis, the elegant black lettering is clearly visible and stands out from the sand-colored building. At night, the lettering shines evenly in bright white, making it easy to read, even amidst the flood of lights emanating from the surrounding skyscrapers. This fascinating alternation between daytime and nighttime impressions has been welcoming the flow of visitors to the Dubai Mall since 2018.

“We were commissioned to replace the previous illuminated advertising with its reddish hue,” says Ameer Ashraaf, who was responsible for the replacement as the project manager for the lighting experts at Blue Rhine Industries from Dubai. “This was by no means an everyday project for us; after all, the lettering on the Dubai Mall is seen by millions of people every year and that brings a high recognition value with it.”

Unusual project

Another unusual aspect of the project was the size of the illuminated Latin and Arabic letters, measuring up to 2.5-meters high and up to 20-meters wide. These gigantic elements were constructed from a reinforced aluminum light box, LED strips and a light-scattering cover made from PLEXIGLAS® LED for backlighting Black & White 7H25 GT.

“This is a version of our brand acrylic glass that was specially developed for illuminated advertising, and which also enables color-changing effects,” explains Matthias Schäfer, Market Segment Manager Visual Communication in the Acrylic Products business area. When unlit during the day, the material appears to be black or dark gray. However, when the lighting is turned on when darkness sets in, the advertising sign shines brightly in the color of the LEDs used; in the case of the Dubai Mall, this is white.

Material with UV protection

This color change remains unaffected by even the extreme climactic conditions in Dubai thanks to the PLEXIGLAS® material’s own UV stability: the black does not fade and the white does not turn yellow. This is a key factor for illuminated advertising in the Middle East, as expert for illuminated advertising, Ashraaf explains: “Temperatures and solar radiation are very high during the summer months. This is why products without UV protection are faced with problems, such as discoloration and stains on the surface.”

In comparison, the brand acrylic glass offers long-lasting protection of the lettering and prevents discoloration and surface damage – with a 10-year guarantee. “That is why I consider PLEXIGLAS® to be an excellent choice in this part of the world. And the 10-year guarantee on colorfulness is unsurpassed,” Ashraf adds. Illuminated advertising that even survives in the desert thanks to PLEXIGLAS®.

Black by day

The black color of the letters reinforces the contrast between the individual letters and the background. The lettering is also easy to read, even in bright sunlight.

Precision with every letter

Blue Rhine only had 25 days to produce and install the lettering, and the team worked around the clock to guarantee the required quality, despite the short time span.

Aluminum and PLEXIGLAS® Black & White

Every letter was made in such a way that it can be installed on the curved sections of the façade. The combination of aluminum and PLEXIGLAS® make it possible to mount the lettering at any place on the front of the building, irrespective of whether the surface is curved or flat. Visitors can therefore find their way to the shopping center no matter what direction they are coming from.
