Review on 🌟 EEEKit 4 Pack 3D Night LED Light Lamp Base: Colorful Remote Control & USB Cable Included for Acrylic and Plexiglass Art, Decorative Lights for Room, Shop, Restaurant (Black) by Nicole Muhammad

These sheets were used as gifts along with 1/8" Laser Cut Acrylic Sheets. The slot is just over 3" wide and on the inside end of the slot there is something on the left and right that "grips" the 1/8" disc and holds it securely. They work well, but please note that the power cords do not include a USB plug adapter. If you already have one, no problem, but I gave them away so I ordered some extra adapters in case the recipients don't have them. .Also, the base must be positioned so that the sensor (3 small holes under the power button) is on the same side of the base as the remote control. The remote control needs a direct line from it to the sensor to work properly. Note in the images that the panels are about 7 inches above the light base if you want to see how they light up the image.
