Description: The PMMA acrylic sheet provides a visual 3D effect, especially in the dark or when taking pictures. It is not made of glass, but a solid piece of acrylic material. It is robust, rigid, and very resistant, not easily broken and does not harm children. It has extremely low thermal conductivity, so it does not heat up even after prolonged use. The soft, warm light does not hurt your eyes. Smart touch button: Press the button to change color. The first press turns on the light and the second press switches to another color. By removing the protective film on both sides of the acrylic sheet, the light becomes more transparent. The 3D effect is only a visual effect; the object itself is a flat acrylic (plastic) sheet. Features: 7 color changes: red, green, blue, yellow, cyan, pink, white. Flashing color change mode: Press the touch button to the last color to enter automatic color change mode. Powered by USB: You can connect it to a USB outlet or a computer's USB port with a USB cable. Energy saving: Power consumption: 0.012 kWh/24 hours; LED life: 10,000 hours. Package contents: 1 3D lamp, 1 USB data cable, 1 user manual
