New Price: ¥4,799 Sotipevs High-Intensity Light UV-Free 15000 Lux Adjustable Bright Light Bedside Lamp LED Daylight Lamp Color Temperature and Brightness Adjustable Applicable for Office/Jet Lag/Reading/Yoga/Creative Activities I bought this because the days are shorter in winter, and I often feel depressed, but I haven't used it since I first turned it on, so I'm selling it. You can switch between several brightness and light color settings. There is also a timer function to turn off the light. It's a very bright light for its size. A power adapter is also included. There is no instruction manual or the original cardboard box. Reference: https://www.amazon.co.jp/dp/B0BRXF8YCM?ref_=ppx_hzod_title_dt_b_fed_asin_title_0_0&th=1 Thank you for looking.
