Product Review

Don't be fooled by cheaper copy-cat flashlights. They might look similar, but this is the Original quick release Beta QR launched by Prometheus Lights on Kickstarter.

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. 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 spring is replaceable if it ever becomes damaged.
