Small, Detachable & Powerful

The first Beta-QR was a stellar flashlight, but there’s always room for improvement. Now built with a custom-machined brass connector and a 302 stainless steel split ring instead of the original carbon steel, the second iteration brings more durability and precision. For a well-designed flashlight that's always at the ready, slide a Beta-QRv2 Quick-Release Flashlight onto your keychain or slip it into a pocket. 

Note: At checkout, choose between electroless nickel and HAIII black.

Quality Construction

Each flashlight is CNC machined from anodized aluminum or electroless nickel. A Nichia 219 LED shines through the glass window and is controlled by a microprocessor. You can switch between brightness modes by turning off the light and turning it back on. The body is attached to the key loop by a brass quick release, allowing you to easily detach it when the need arises. the light also takes a standard AAA battery for convenience. On the Color Rendering Index, a measurement of how accurately a light source renders the full color spectrum, daylight scores a perfect 100. While not quite the sun, the Beta-QR is no slouch at a 93, giving you a handheld device with a beam as bright as you need, when you need it.
