Geo LED wall light - a perfect optical illusion The small LED wall lamp Geo from GROSSMANN is a perfect optical illusion, because at first glance it seems as if the wall lamp is a three-dimensional light object, but on closer inspection you will see that this is not the case at all. The deception succeeds through the use of three equally large, diamond-shaped elements, which in their arrangement perfectly simulate the image of a cube. A light surface and two aluminium rhombuses brushed in different directions make it possible. Integrated here are two efficient LED modules that emit their warm white light glare-free upwards and downwards. The LEDs can also be dimmed using an external phase dimmer. The LED wall lamp Forte is an impressive design \"Made in Germany\" by the lighting manufacturer GROSSMANN.
