Effectiveness is our goal!

TDC is vigorously developing company which sets itself gradually higher demands in all fields of its business. We know that signage is the most important for safety thus we are constantly broadening our ware and uprate lightning parameters of our photoluminescent signs. Currently, all of our glowing signs exceed the requirements of DIN 67510 norm ten times. In order to facilitate you getting around types and power of our ware, we introduced following designations:


SL/2

Standard glowing technology intended for well and medium lighted rooms (offices, shops, schools etc.).


SL/5*

Upgraded glowing technology intended for:

  • poorly or non-continuously lighted rooms (hospitals, stores, hotel corridors, underground passages, garages etc.);
  • low location-lightning (LLL) Safety Way Guidance System (SWGS);
  • sea ships’ signage.

SL/8*

Advanced glowing technology near very high lightning parameters fulfils requirements regarding surface flammability and toxicity. This technology is intended for:

  • places lighted very poorly, when the bundle of activating light is very small;
  • tunnel signage, underground passages, garages;
  • sea ships’ signage.

SL/8 signs are most commonly chosen by the military and police.
