Launched on Kickstarter in 2013, the Beta QR was the world's first quick release keychain flashlight. The Beta QR has something for everyone - it's designed to be there when you need it and disappear when you don't. V3 feature the newest Nichia 519A 9080 (4000K) LED with 90+ CRI. The primary change is to the light's ergonomics; the head is a slightly larger diameter to make one-handed operation easier in addition to making the light more impact resistant. The added material also allows deeper grooves for improved grip. Fluting at the back also provides additional grip. The quick release works simply by pushing to engage and pull to disengage. The mechanism is engineered to provide 4,5 kg of holding force. Accidental disengagement is virtually impossible, and engagement is verified by a solid click every time. The spring is user-replaceable if that is ever required. A "High CRI" LED is designed specifically to work in concert with the human visual system, providing the maximum possible color accuracy when compared to sunlight. Daylight scores a perfect 100. The Beta QRv3 is part of Prometheus Lights "QR Compatible" ecosystem. There is a variety of accessories that take advantage of the QR like pocket clips and Kappa QR Keychains.
