I received this as a commemorative gift last year, but I am selling it because I don't use it. I have only turned it on a few times and have hardly used it. Thank you for your consideration. Ambientec Xtal XTL-01SLV The following is a description of the product. This is a cordless table lamp with a beautiful, artistic light that radiates from crystal glass. The crystal glass is carefully crafted by skilled artisans, from cutting out solid blocks of high-grade glass to polishing them. The crystal glass and the aluminum metal reflector, which effectively diffuses the light, create a fantastic sparkle and a radiating light. It has a captivating charm, yet it doesn't overstate its presence. Xtal adds color to spaces and tables, transforming familiar spaces such as bathrooms and balconies, and dramatically enhancing the scene. ◾️Brand Ambientec ◾️Designer Ryuichi Kozeki ◾️Size Φ80mm x H82mm, approx. 620g Box: 140mm x 140mm x 140mm ◾️Material Shade: Crystal glass Base: Aluminum alloy, silicone rubber, ABS resin, etc. Light source: LED (Color temperature: 2000K) Dimming: 3 levels Lighting time: LOW 32 hours → MID 16 hours → HIGH 8 hours Charging method: USB charging (AC adapter is not included) Charging time: 3 hours * Can be lit continuously while charging Power supply: Rechargeable lithium-ion battery 3.7V/190nAh Waterproof performance: Waterproof IPX6 equivalent, suitable for use in bathrooms and outdoors * Body only Accessories: USB charging cable (Type C), dedicated charging stand
