The Glaçon's effect depends almost entirely on bulb choice — pick clear (non-frosted) E14 LED filament bulbs. The visible filament is the design centerpiece; frosted bulbs hide the filament and ruin the captured-bulb effect.

Recommended specs: clear E14 LED filament tubular ("T") shape, 2700K-3000K warm white, around 4-6W (40-60W incandescent equivalent). Search for "E14 tubular filament LED" or "E14 candle filament LED clear" at any major lighting retailer.

Cube needs 4 bulbs · Cylinder needs 8 bulbs. Buy enough to populate every well — empty wells are visible through the crystal.

The two sizes are distinct sculptural forms, not just dimensional scaling:

The Cube (15.5 × 15.5 × 17.5 cm · 4 bulbs): a compact square block with bulbs in a single 2×2 layer. Reads as a quiet jewel-like object — best at bedside, on a console, or as a generous gift.

The Cylinder (12 × 10 × 39 cm · 8 bulbs): a taller column with bulbs stacked across two layers (4 + 4). Reads as architectural statement — best on a wider console, sideboard, or entry table where the height can be appreciated.

Both share the same crystal and brass material vocabulary; the choice comes down to whether you want a quiet jewel or a tall statement.

Push-button switch on the cord — toe-tap or hand-tap to turn on or off. The lamp ships with a 150 cm / 59″ cord and switch plug ready for a standard wall outlet.

The lamp itself is not dimmable. For ambiance variation, use dimmable E14 LED filament bulbs paired with a plug-in dimmer module (or smart bulbs with app-based dimming) — at lower brightness, the Glaçon looks especially atmospheric, like banked candles in glass.

Optical crystal stays brilliant only if dust-free. Switch off and let cool, then wipe down all faces of the crystal with a soft microfiber cloth — slightly dampened with distilled water for stubborn smudges.

For deep cleaning, use a 50/50 distilled water + isopropyl alcohol mix applied to the cloth (never sprayed directly onto the lamp). Avoid abrasive cleaners or paper towels which can scratch the polished surfaces. To clean inside the bulb wells, remove the bulbs and use a soft cotton swab.

The Glaçon is a focal-point sculpture lamp — best where it can be seen up close in 360° and where its captive-bulb effect can register:

Cube: bedside table, executive desk corner, dressing-table accent, dining sideboard at place-setting eye level.
Cylinder: entryway console, hallway accent, sideboard pair flanking artwork, lounge end-table at sofa-arm height.

Reflective surfaces under the lamp (polished marble, mirror, glass tabletop) double the visual effect by bouncing the captured-bulb pattern downward.
