They’re pretty cool for adding lighting effects to your scenes and you can easily connect to them to just about any lego compatible brick. You can make them in several colors and turn them on with a tiny button on the side. Compared to official light bricks, these diffuse the whole brick instead of just being a spotlight. They’re both the same size but offer different types lighting. The lego light bricks are great for pointing light, while the 3D printed brick glows brighter and can fit in tighter spaces. But you can connect them together to make interesting combinations that illuminate your projects. You can 3D print the bricks using opaque filament on almost any desktop 3D printer.
