This small paper lamp with square base 3.5cm x 3.5cm and 5.0cm height.
My lamp is cut by laser.
The size is so small that It can place on breadboard as electronic project.
U can make a breadboard compatible lighting unit with LED and 330Ohmn resistor.
or using 1W High power LED with 3V button battery.
U can also make a paper house lamp with window.
(Maybe u would like to stick a piece of white A4 paper on the window frame)
