There are some cases of decorative luminaires, lanterns or projectors that cannot be equipped with a standardized ZHAGA or NEMA socket from the factory. However, since the ZHAGA connector for Luminaires is much smaller than its NEMA equivalent, there are very few luminaires that cannot be equipped with the ZHAGA connector from the factory. However, Tellink has exterior mounting kits availabe for this special luminaires, thus allowing the use of ZHAGA or NEMA standard Tellink controllers.
