I printed this lamp using transparent orange filament hoping it would emit more light than regular filament. And it does! The first photo show the lamp with no internal light, and the second one shows the lamp in a dark closet with the light on.
The lamp sits on top of a standard 68mm/2.75" diameter LED puck light that is powered by 3 AAA batteries. I bought 3 of these lights at Lowes for $9.98 batteries included. Here is a link to the puck light:
