The professional exterior lighting LED system light chain differs in 230 Volt series or low voltage systems with 24 Volt. The 230 volt systems have stronger cables and the LED lights are larger and brighter than 24 volt systems. Our 230 Volt Tech-line professional outdoor lighting system has no transformer and can therefore be expanded very flexibly, Tech-line can light up to 8,000 Leds lights on one socket. The low voltage systems like Top-Line have a transformer and can light up to 2.000 LED lights on one socket. Of course both systems can be extended infinitely but it requires several sockets. Both systems are very energy efficient and shine in a very nice warm light (warm white) colour. Expandable professional outdoor lighting can be used in the garden, for example in trees, plants or staircases up and down stairs. Supply lines of different lengths bridge the path from the first socket to the illuminated object. There is a wide range of accessories to extend the light chain to 5 more light chains. There are not only light chains but also LED light curtains and LED light nets. If you are not sure how many light chains you need to realize your project, please do not hesitate to call us. We will be happy to advise you competently.
