15.7 in of liquid-varnished metal draws a single curve and sends a 1 400-lumen glow upward and downward in equal measure. Ferruccio Laviani distills wall lighting to one gesture for Foscarini, twisting an aluminium tube just once to create a subtle “knot” that doubles as a handy grip when you choose the plug-in version. Just 2.8 in wide and 4.7 in deep, Tobia sits close to the surface yet fills the space with warm-white 2 700 K light from its integrated 12 W LED engine, rated for 50 000 hours and dimmable on low-voltage lines. Pick the mood: satin black, crisp white, or brushed gold. Use a single fixture as a bedside accent, line a hallway for way-finding, or stack two at different heights to animate a stairwell—the up/down beams paint a soft hourglass of light that changes with every wall texture. Hard-wire straight to the junction box or order the optional cord-set for rental-friendly mounting; the slim back plate hides the driver either way. Wipe the durable lacquer with a damp cloth and the lamp is ready for its next decade of quiet service.
