The flashlight is a Kickstarter project and will be available from February 2016 onwards for a basic price starting at $35. The flashlight consists of two parts—a 5mm battery-run CREE LED with lumens of 3000mCd and a small tritium tube which is always lit. The tritium light is a small glass vial tube with tritium gas and a phosphor layer. The tube will produce a faint light for almost a decade without any additional energy or power. The tritium tube enables you to locate the torch in pitch darkness.
