Thank you for viewing. This is an LED light made with a 3D printer (PLA) and acrylic (light-emitting surface). Power is supplied at 5V. A dedicated power adapter is also included. * LEDs generate heat. After using for 2 hours, turn it off and check the back to make sure it's not hot. * Do not connect the USB to a computer. There is a risk of malfunction. Please use the power adapter. * Do not use during thunderstorms. * Do not handle with wet hands. * Use out of reach of small children. * This is a handmade item, so there may be imperfections. Please purchase only if you understand this. I can also create LED lights with other desired text. Feel free to comment with your requests.
