The lights can be connected in any pattern, straight, L shaped, square etc, using the included connectors. The light operates with an on/off switch and has selectable dimmer. Each light tube rotates to point the light exactly where you need it. Power this light using the power module and AC adaptor (both included). Mount with the fez mount slide in/slide out bracket. The ultra slim profile allows you to place the light inconspicuously wherever you may need extra light.
