Light upwards and downwards: LED wall luminaire SML² The LED wall luminaire SML² combines the latest technologies - both in terms of LEDs and heat sinks - with the best possible functionality. The warm white LEDs achieve a colour rendering index of at least 90 Ra and are comparable to halogen bulbs in their brilliance. Due to the specially developed heat sinks, only little heat is generated during operation, which also increases the durability of the LEDs. The light is diffused symmetrically upwards and downwards. SML² can be dimmed with a phase-cut dimmer if required. The SML² model can be used universally and is particularly suitable for corridors and staircases, both in private rooms and in public buildings.
