CORTE 31-50731, from the Candellux Studio line, is a pendant built around a single element: a slender glass tube with a 6.5 x 6.5 cm footprint, hung on a thin cable beneath a matt black canopy. The glass is clear and textured on the inside, and the built-in LED module delivers 600 lm from 10 W in a warm 3000 K.
Clear glass — the source is part of the design
The shade does not hide the diode, it shows it. The internal texture of the glass breaks the light into small highlights, so a lit tube reads as a glowing column rather than a flat patch. This is a decorative solution: clear glass gives more sparkle and less diffusion than opal, so the lamp belongs where it is meant to be seen rather than where it simply has to light something.
600 lm — accent light, not general lighting
Ten watts give 600 lumens, roughly 60 lm/W. That is about what an old 45 W incandescent produced — enough to mark a spot over a worktop, a bedside table or a staircase, not enough to light a room. Over a kitchen island or a long table the natural answer is a row of several; the narrow 6.5 cm tube is made for exactly that arrangement.
3000 K is warm white, close to a classic incandescent tone. It works well with the matt black fittings and with wood, and does not cool a room the way neutral 4000 K does.
A drop adjustable up to 200 cm
The manufacturer quotes 200 cm as the maximum height and states plainly that the height is adjustable. In practice the cable is shortened at installation to whatever length you need, so the same lamp will hang low over a table in a room of ordinary height and high in a space with a mezzanine or over a stairwell.
The source is permanently built in
This is an integrated-LED luminaire — no socket, no bulb to change, and it lights from the first switch-on. The manufacturer declares an LED life of 20,000 hours, which at three hours a day is around 18 years. It is worth being aware of the other side of that: when the module reaches the end of its life, it is the whole fitting that gets replaced, not a bulb.
Build
Metal and glass: a matt black steel canopy and tube fittings, and a clear glass shade. The whole thing weighs 1.03 kg net — light enough that mounting needs no special anchoring. The lamp comes from the Polish company Candellux of Wołomin and carries the Candellux Studio label.
