This is a LED table lamp that uses a remote controlled LED that can change colors, change brightness, and turn on and off. Here is the LED unit:
It requires 3 AAA batteries. Here is a short video of the lamp in operation:
The colors are actually much better than the video shows; my phone's camera just couldn't handle the lamp's dynamic range very well.
The LED unit fits inside the lamp and can be easily removed. The lamp printed in slightly less than 11 hours using a layer height of 0.200 mm. I used white PLA filament, but clear is also a good choice. Other colors work OK, but they do affect the colors of the LED unit.
