This is an older Project i made based off a design i saw on the net, i ended up doing a how to for make magazines blog on thier website, i re-named it the Mad Scientists Night Light.
Close up of the tube lamp light bulbs, when dimmed down. the bulbs lifetime is drastically increaded do to the low voltage, and they emit a nice soft glow, the filaments glow softly and thier paths are easily traceable throughout the bulb.
The light bulb sockets set in the cut out holes, i made sure when i cut the holes they were just too small and then lightly hand sanded them till the sockets just fit in properly with a few millimeters of the white socket exposed, then used a light bit of clear glue around the entire socket and the inside of the hole to attach it as well as a thicker ring of glue around the sockets on the inside of the box.
The light sockets themselves were purchased from Lowes and are fairly cheap as well ($2 or so) and are designed for ceiling lamp repair and replacement.
