The POWERTRONIC PT-FIT S is an electronic control gear (ECG) that you use with high intensity discharge lamps and install within the luminaire. With an energy efficiency index of A2, it gives you a great cost/benefit balance and is good for use in shoplighting, health and fitness areas (as long as it is installed in a dry and corrosion-resistant area) and for the creation of effect and accent lighting. The compact size and light weight of this ECG make it easy to install in even small luminaires, and the POWERTRONIC PT-FIT S provides the reassurance of automatic safety shutdown of lamps in the event of defect or end of lifespan.
