The "Twist Tube Light" is a conceptually brilliant, versatile flashlight. Incredibly flexible and hardwearing, the light can be contorted and bent into those hard-to-get places that you need to illuminate and would always struggle to reach with a conventional torch.
It has a soft foam exterior designed to avoid sliding off or scratching surfaces, which makes it particularly useful in the difficult circumstances where you need to light up something specific, delicate and hard to get at, and is even 100% waterproof and floats in water. As opposed to being ergonomically designed, the Twist Tube Light adapts to the ergonomic demands, making this the definitive useful flashlight for any circumstance.
