- 🇰🇷 KR· 14 Aug 2026
Order and delivery: aug 09 ~ aug 13, 2026. It took 4 days for delivery. It worked as described and as expected with 10 levels of brightness steps. Short-pressing adjusts the brightness step by step and long pressing seamlessly at once. It was better than my expectations.

Fast delivery. The product was well packaged for shipping. Aesthetically pleasing design. Multiple levels of dimming and brightening the light, as well as the option to turn it off. The power button is backlit and easy to find at night to turn on the light. Versatile use.
