Prometheus-Lights Beta QRv2 (Electroless Nickel Plated)
THE BETAQRV2 WAS CONCEIVED WITH ONE GOAL: BE THE BEST KEYCHAIN FLASHLIGHT ON EARTH
This tiny and functional light retains all of the core qualities of a custom Prometheus light: the aesthetic appeal, thoughtful design, and superior beam quality. The concept came to me through observation, research, and conversation. I tried carrying other keychain lights. They were handy to have around, but always got ditched from my key ring... because when I need light I don't want it stuck to a wad of keys. Keychain lights just don't work like I need or want them to, so Prometheus Lights came up with something that does.
The Nichia 219B High CRI (92+) 4500K LED provides a warm, natural light with excellent colour rendition!
Two Things that Separate the BETA-QR from the Pack!
1) It's a (patent-pending) Quick-Release Flashlight: Normally a keychain-light is a compromise: close at hand, but often useless and frustrating because the light is shackled to your keys. The Beta-QR is a "real" flashlight that hangs out on your keychain till duty calls.
The Quick Release is a tried and true design and an elegant solution to the problem. The QR lets you use the light how you naturally want to use it, you don't have to fight with it. It's so simple, that it's awesome.
2) The state of the art Nichia 219 High CRI LED: The 219 is a bit of semiconductor magic that turns the idea of "bad quality LED light" on its head. People hate LEDs for the same reason people used to hate fluorescent bulbs... the light they produce is absolutely horrible. Fluorescent lights have changed, and so have LEDs. It's time to stop living in the dark ages. Yes, that was a flashlight pun.
The QR Spring!
The canted-coil-springs are custom manufactured specifically for the Beta-QRv2 by a US company who specializes in canted coil springs...literally the only product they make. Normally these are found in connectors for military, medical, and aerospace applications. This little beauty is the single most expensive component of the Beta-QRv2.
These are manufactured from 302 Stainless Steel: drawn, coiled, cut to length, and the ends are laser welded together. It's a ridiculous achievement in manufacturing to make something this tiny... and then weld it together so the diameter of every spring is accurate to within less than the thickness of a sheet of paper.
