Luminaires designed and manufactured by R. Stahl Tranberg are intended for use in rough environments, and to meet applicable international standards. The new LED floodlight TEF 9970 by R. Stahl Tranberg sets a new standard in the industry as it has a wider operating temperature range, along with several new features.
The LED light source provides a hugely longer lifetime expectancy than xenon light bulbs, while the special designed optics ensure an ideal coverage of the helideck surface without giving glare to pilots in the critical landing process. As an option, a dimming functionality may be installed, which reduces light output to 50% when and if required. The operating voltage span is wide, and absorbs voltage variances and spikes without resulting in flickering or changes in light output.
The innovative design is also great news for service and maintenance personnel, as it is a sealed unit which requires no inspection of traditional flame paths.
Helideck equipment manufactured by Tranberg is delivered to offshore installations, oil tankers and supply ships, hotels and hospitals landing areas all over the world.
