Designfor a Modular lightning system “barra”

Some years ago I developed the design of lightning systems. I created two lines:
One I called “ball” and another one “barra”.
The “barra” system was made for various lamps, cool light, spot light (12 V DC) and halogen lamps with higher performance.
The system included standalone wall light, stand light, and a rail system for down and spot light.
