The Steng Tolou Ceiling Lamp has a ring-shaped fabric lamp shade. It emits light both downwards as well as upwards. The lamp is suspended from the ceiling with a cable. The cable is directed to the side of the lamp shade via a deflector and is shortened to the desired length during installation. The manufacturer Steng recommends shortening the cable between the ceiling bracket and the cable diverter to 3 cm or 5 cm. As the cable is supplied with a maximum length of 200 cm, the lamp can also be individually suspended with a different distance if required.

The Tolou Ceiling Light is offered in the shade colours black or white. Its shade is 7.1 cm high and has a diameter of 46 cm. On request, the ceiling lamp is also available in other shade colours and diameters. As standard, it is supplied with a cable diverter in chrome. The cable diverter is also available in gold or black on request. The integrated LED is offered with a colour temperature of 2,700 Kelvin extra warm white or 3,000 Kelvin warm white. On request, the lamp by Steng is also available with 4,000 Kelvin white.

The Tolou Ceiling Lamp is offered with three versions: on site dimmable with a trailing edge or leading edge phase dimmer, DALI dimmable or with a Casambi module. The DALI dimmable version requires a 5-core mains cable. With a Casambi module, the lamp can be operated by smartphone or tablet using the Casambi app via Bluetooth. Casambi technology also offers the option of switching and dimming several suitable lamps separately in groups.

With the DALI dimmable version and the one with Casambi module, the uplight and the downlight of the lamp can be switched separately. On request, the version with trailing edge or leading edge phase dimmer is also available with a push button switch for separate switching of uplight and downlight.
