The Zambelis 25447 is a linear pendant: a glass tube 124.6 cm long and 4 cm wide, closed at both ends with brushed gold caps and hung on two thin cables under a rectangular canopy measuring 20 × 6 × 4 cm. The LED module is permanently built in, so the fitting lights up as soon as it is connected.
How long it is and where to hang it
The lit tube measures 124.6 cm — a figure to compare with the length of your own table top; a linear pendant looks right when it is clearly shorter than the table or island it hangs over. The cables allow a drop of up to 200 cm from the ceiling and are shortened during installation.
Above a table the lower edge is usually set 70–80 cm above the top: the light then covers the whole surface and the tube stays out of the eye line of people sitting opposite each other. The canopy is 6 cm wide and covers only a narrow strip of ceiling, so the installation box needs to sit reasonably accurately on the axis of the fitting.
How much light it gives and how to dim it
The luminaire draws 33 W and delivers 2460 lm at 3000 K, a warm white. That output is enough to light a whole room — for comparison, the old 60 W incandescent bulb gave around 800 lm. A colour rendering index of Ra 90 keeps the colours of food and worktop true, which counts over a table and over a kitchen island.
Light leaves all the way around the tube, in a full sphere, so the fitting lights both the surface below it and the ceiling above it. Dimming is TRIAC — a leading-edge wall dimmer of that type is required and is bought separately. The diode cannot be replaced; the manufacturer quotes an L70B50 lifetime of 30,000 hours.
Materials and connection
The end caps and the canopy are metal in a brushed gold finish, the shade is clear glass and the diffuser acrylic in opal white. The luminaire runs on 220–240 V mains in protection class I, so it connects to wiring that carries a protective earth. Weight including packaging is 3.2 kg, and the manufacturer gives a 3-year warranty.
