Office/industrial lighting TopLine

TopLine is one of the latest creations of the designers of Rommtech-3S company. Within its simple and yet elegat design TopLine contains highly efficient proprietary module T8/T5 LED combined with high efficiency specialised current driver and thanks to these qualities TopLine won the golden medal at the International Technical Fair in 2013. With equivalent dimensions TopLine produces the same amount of light with savings of up to 55% of electricity. The module features unique construction, integrated mirror optics, high efficiency diffuser and the latest LED technology with efficiency up to 110 lm/W. Produced in three sizes so TopLine can fit in anywhere. 

Due to the high uniformity of the emitted light and the low overall brightness, TopLine is applicable where the unified glare rating is of importance: schools, offices, hospitals, working halls. Containing no mercury, lead, or glass, LED modules do not present risk of area contamination that is possible with fluorescent lamp breakage.


  • Excellent total cost of ownership with attractive payback times
  • No annoying noises, vibrations and flickering
  • Unified Glare Rating is lower or equal to fluorescent tube
  • Long-life LEDs (with an average rated lifetime of 70 000 - 100 000 hours) reduce the maintenance and product replacement costs that are associated with fluorescent systems
  • Significant sustainability opportunity due to lower energy consumption, reduced waste and elimination of hazardous substances such as mercury and lead
  • Overall, the usage of LEDs helps to reduce the internal heating in the premisses.
  • 100% efficiency - directed light which guarantees that all of the luminosity goes where you need it
