Xtal Acrux is a compact, rechargeable cordless table lamp by Ambientec, designed by Ryuichi Kozeki. Its crystal glass shade begins as a solid block, cut and polished by skilled artisans to catch light from different angles.

Ambientec's proprietary double-sided LEDs emit light in all directions, while an aluminum reflector diffuses the glow into a shifting shimmer. Place it on a dinner table, bedside surface, or balcony table to bring warm light to an everyday setting.

Each piece is handcrafted, so subtle differences may occur even within the same model.

Three Brightness Levels

Choose LOW, MID, or HIGH to adjust the brightness while retaining a warm 2000 K color temperature. In battery power mode, continuous lighting time varies with the setting:

• LOW: Approximately 32 hours
• MID: Approximately 16 hours
• HIGH: Approximately 8 hours

Battery and USB Power Modes

Use battery power mode for cordless lighting, or USB power mode for continuous illumination while the charging stand is connected to power.

• Battery power mode: The lamp automatically turns off when placed on the charging stand and turns on when removed.
• USB power mode: The lamp automatically turns on when placed on the powered charging stand and turns off when removed. In this mode, continuous lighting time is not limited by battery runtime.

USB charging takes approximately 3 hours.
