Remarks:
* Unlike filament shuttles that have rotational symmetry about its axis, to ensure the orientation about its axis of this LED shuttle,
* DC-powered, think back to the shuttle if it does not work to reverse its sense of connection to the support,
* Check the available width (17 mm) of the LED wafer, and check the available space below 3 mm more compared to conventional cylindrical shuttle due to the presence of welded components in the LED board
After 2 months of use: still works as well.
