LED Essence wall light with indirect lighting effect Essence is an LED wall light with a very minimalist design that emits indirect lighting through the LEDs installed towards the wall. Like the wall mount, the long, tubular body is made of powder-coated aluminium and the warm white LEDs are covered with an opal white acrylic light diffuser. Glare-free and effective, the LEDs shine evenly through the diffuser onto the wall and only indirectly into the room, creating very pleasant lighting and a decorative light pattern on the wall.
