The Salt lamp is a reimagined icon of portable lighting, designed to combine sculptural elegance, advanced technology, and a uniquely calming lighting experience. Compact yet powerful, it can be used almost anywhere—by the bedside, on a dining or coffee table, in the bathroom, on the balcony, or even as a decorative accent on the windowsill. Wherever it is placed, it creates an atmosphere of warmth and well-being, making it an essential companion in both everyday life and special moments.
What sets Salt apart is its extraordinary performance. With a maximum output of 450 lumens and up to 150 hours of battery life on medium settings, it is one of the most powerful and efficient mobile lights available. On its lowest dimming level, Salt provides an unprecedented 500 hours of continuous light. At its core lies a new-generation USB-C Power Delivery battery (9V / 12V, 2A), capable of recharging fully in just two hours. The light communicates battery status through an intelligent LED indicator that briefly illuminates when in use: green for 100–20% charge, orange for 20–5%, and pulsating orange for less than 5%.
Designed for intuitive interaction, the entire head of the luminaire is ultra-touch sensitive. A simple tap turns the lamp on or off, while a gentle swipe or long press allows smooth dimming adjustments. In addition to brightness control, the lamp also offers color tuning. A discreet “Magic Button” on the rubberized base lets users switch between three dimming curves—Clear Light, Golden Light, and Sunset Orange—tailoring the mood to any setting. This versatility is further enhanced by integrated Sunset Dimming technology, which reduces blue light content as brightness decreases, simulating the natural warmth of sunset. The resulting light spectrum has been proven to encourage the release of melatonin, supporting a healthy circadian rhythm and easing the body and mind into rest. A 30-minute timer function can also gently guide you into sleep.
Salt’s surfaces reflect the same dedication to craftsmanship and sustainability that define its lighting technology. Made from durable, pollutant-free aluminum, it is available in powder-coated or polished finishes that are refined and long-lasting. The lampshade’s matte finish ensures soft, glare-free light diffusion, while the lamp’s Powder Skin surface provides splash resistance (IP21). This makes Salt suitable for both indoor and outdoor use, even able to withstand light rain showers.
More than just a portable lamp, Salt is a thoughtful lighting companion. It embodies refined German engineering, designed and manufactured at the GRAU campus in Hamburg, where sustainability and design precision go hand in hand. By integrating four battery units, it delivers twice the power output of typical cordless lamps and 50% more battery performance than its predecessor.
Every detail has been optimized for modern lifestyles: its lightweight build of 0.8 kg makes it easy to move, while the compact design ensures it fits seamlessly into any environment. The lamp also supports flexible charging, supplied with a USB-C cable and optional power supply, ensuring compatibility across devices.
With its sculptural form, intelligent functions, and wellness-focused lighting spectrum, Salt is far more than a source of light. It is a mobile object of design and comfort, engineered to provide a soft, calming glow that adapts to any mood, moment, or environment. Salt redefines the standard for portable lighting—smart, sustainable, powerful, and beautifully crafted.
