With my team at Licht+Raum we developed this patented locking mechanism for lamps
The LR. Click ® locking provides users the ease of installation in one swift ‘click’. Once the housing is installed, the lamp simply clicks onto the housing without the need of any tools. During in which the electronical contacts will instantly connect and is now ready for use. This system housing is designed to interchange with other Licht+Raum lamp designs.
