Purist LED hanging light Compendium as practical, functional table lighting What makes the LED hanging light Compendium particularly suitable for table lighting is, of course, its slim, elongated form. Visually, the slender metal rod appears to have been fitted with just one - slightly protruding - reflector, which is located above the bright, warm white LEDs. In the normal state, the light emission is set so that Compendium illuminates the table surface. Das is of course very practical at many times, but it doesn't have to be. If you prefer a more indirect light or want it to shine to one side, you can set this up when installing the hanging light.
