Cachalot in Dark Gray is a rechargeable portable lamp by Ambientec, designed by Yoshiki Matsuyama. Inspired by the sperm whale, its smoothly curved acrylic shade brings a sculptural presence to the room by day and a soft, warm glow after dark.

The light follows the flowing lines of the shade, creating a quiet focal point for an evening at home. Place it nearby as you wind down, or use it on a table to bring gentle illumination to the space around you.

Design and Materials

The dark gray shade is made from high-purity acrylic resin. The base combines zinc alloy, aluminum, and silicone rubber with a copper-plated finish. A specially developed LED provides warm light at a color temperature of 2000 K.

Brightness and Power Modes

Cachalot offers different brightness settings depending on how it is powered:

• Battery power mode: LOW and HIGH. Continuous lighting time is approximately 24 hours on LOW or 12 hours on HIGH.
• USB power mode: LOW, HIGH, and EX-HIGH. Continuous lighting time is not limited by battery runtime while connected to USB power.

USB charging takes approximately 3 hours. The rechargeable lithium-ion battery is rated at 3.7 V / 190 mAh.
