STvario LED O
Future-oriented light for road traffic
The new generation of powerful traffic signal save energy, help to protect the environment and are very easy to maintain.
More efficiency
Due to the use of LEDs, the lifetime of the STvario LED O system is considerably longer than that of conventional signal lights. That saves energy and operation costs too. A long lifetime minimises the probability of signal failure and therefore ensures greater safety. Undesirable phantom effects are excluded through the use of neutral coloured lenses. The STvario LED O signal head meets the highest standards while minimising power consumption.
The signal heads made by Stührenberg are designed for signal light sizes of 200 mm and 300 mm in diameter. All symbol masks defined in the German Directive on Traffic Signal Systems (RiLSA) (and more) are available for both sizes.
