The calculator prices this lamp at 16 metal fragments, and you will never spend them. That is the value the data puts on the empty tuna can, but no player can craft a can. Every lamp starts with a Can of Tuna somebody ate, so once you plan a few lamps, drop the empties into a box instead of the furnace.
The blueprint is a cheap research with no bench, easy to take in the first scrap run. The low grade fuel comes four to a craft: two lamps use it exactly, while one leaves a couple over.
No can to spare tonight? The lantern lights the same room from fuel and frags with nothing to learn, though it stands on the floor instead of hanging on a wall.
