SURVIVAL TIN LAMP The Survival Tin Lamp (STL) is a Research & Development Project by Karl OscarDelta to build a compact, lightweight and simple modular light source for a small survival/escape & evasion kit that can be carried on the person, powered on/off when required and provide constant light source for 72 hours+. On the 19th July 2022 at 2100hrs the STL reached 2,400 hours! - 100 Days... The STL kit consists of 1 x Battery Holder (3D printed) and 2 x Light Emitting Diode (LED). The STL can be powered with an easily sourced CR2032 Coin Cell Battery (not included). The complete kit can be carried inside a Soda Cap Stash. There are no switches. Simply make contact with the LED and Battery: - Put the Anode lead (long part) on the (+) positive side of the battery cell. - Put the Cathode lead (short part) on the (-) negative side of the battery cell. - Now slide the battery into the holder - The Battery Holder will maintain the connection and allow for the LED to stand upright. A single CR2032 Coin Cell Battery will provide light throughout the night if required. Most of the light is directed OTF (out the front). With STL DIFFUSER you can scatter the OTF light for a more even ambient lighting. At room temperature a single white LED will run for more than 200 hours* and unlike a candle it will not blow out and will even work when submerged underwater! Note: During this R&D project variations in the LED and Battery Holder will occur.
