Square surface-mounted LED panel Slim with indirect light effect This LED panel Slim for ceiling surface-mounting is characterised by its ultra-flat design. It is fitted with cool white LEDs and is therefore ideal for use in rooms where low-fatigue light is required for working - for example in kitchens, work or utility rooms or corridors. The satinised diffuser emits uniform general lighting into the room, while the indirect upward light creates an effective ring of light on the ceiling and indirect room lighting.
