Fully functional Nuka Cola Lamp seen throughout Fallout 3. Bottle made using acrylic resin poured in a mold of a 500 ml Coke bottle. I didn't bother placing a label on the bottle sine none of the lamp in the game have one.
Using a sponge to do a dry brush technique with brown paint would work as well. Similar to the way I painted the Fixer tin, but with even less paint. Your idea to make a night light sounds good. I’d love to see a picture of it once it is completed. This lamp I made here is about 32 inches tall from the base to the top of the lamp shade.
