If you're in the market for a keyring flashlight that is capable of emitting substantial amounts of light while remaining compact and cost-effective, look no further than the Sub, a product that is allegedly the world's smallest flashlight.
Powered by a trio of coin cell batteries, this particular keyring flashlight can pump out 30 lumens of illumination, which comfortably beats out the output of many bigger flashlights. What's more, the flashlight is housed in an aircraft-grade aluminum casing that is dustproof, dirtproof and waterproof up to a depth of one meter.
Currently the subject of a crowdfunding campaign over on Kickstarter, the Sub is a fantastic example of an age-old technological product being adapted to the needs of the modern consumer.
