Product Review

The world's first quick-release keychain flashlight. Our innovative mechanism is simple to use and reliable. Simply push to engage, pull to disengage. Up to 10 lbs of pull means the flashlight detaches only when you're ready.

Bring unparalleled clarity with you everywhere. Prometheus Lights Beta Flashlight provides superior color reproduction and beam quality in a compact and convenient form factor. The High Color Rendering Index (High CRI) LED is designed to work in concert with the human eye to provide maximum possible color accuracy. Daylight scores a perfect 100 on the CRI scale. The Nichia 219 used in the Beta provides 90+ CRI.It's currently the highest CRI per lumen in the industry!

Our flagship Beta flashlight has all the qualities you've come to expect with Prometheus Lights: aesthetic appeal, thoughtful design, and superior beam quality.

From the maker himself, Jason Hui: "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!"

BATTERY TYPE: USE AAA Lithium (disposable) or NiMH (rechargeable). We recommend ENELOOP or GP ReCyko+ RECHARGEABLES.

DO NOT USE LITHIUM ION OR ALKALINE BATTERIES. Our high-performance keychain flashlight is the Gold Standard for anyone who depends on clear, bright light they can carry anywhere.
