Description

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 Beta-QR was conceived with a simple goal: be the best keychain flashlight on earth.

Please Note: The QRv2 is not backwards compatible with the original Beta-QR. I considered this in the design, but the engineering of the QRv2 system requires a very specific groove design to function properly.

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 I came up with something that does.

Simply push to engage and pull to disengage. The mechanism is engineered to provide 10 lbs. of holding force. Combine this with the snag-free profile of the brass component and accidental disengagement is "virtually" impossible, and engagement is verified by a solid "click" every time!

The retaining is replaceable if it ever becomes damaged. The brass connector is now machined by the flashlight manufacturer and no longer supplied by a third party vendor.

302 Stainless steel "flat" split rings replace the original carbon steel "round" rings...because flat stainless split rings are more awesome (and more durable).

My 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. The springs on your screen are about 10x the actual size. 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.

Two things separate the Beta QR from the pack.

  • 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.
  • 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.
