Beta QRV2 635NM: Red
THE BETAQRV2 WAS CONCEIVED WITH ONE GOAL: BE THE BEST KEYCHAIN FLASHLIGHT ON EARTH
THIS BETA VARIANT HAS 3 MODES AND FEATURES A CREE XP-E 635NM RED LED.
This light is perfect for people who venture into the dark and need to preserve their night vision: pilots, astronomers, photographers, videographers, etc. The low mode is designed for reading up close in the dark. The two higher modes will give you more range. The highest mode is enough to light up an entire room.
WHY RED FOR NIGHT VISION?
The "true red" 635nm wavelength reduces rhodopsin bleaching in your eyes, the effect that helps you adjust from night vision to day vision. If you are working in the dark and are exposed to bright white light, your eyes will switch over to day adapted vision. Going back to night adapted takes about 30 minutes.
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 about through observation, research, and conversation.
Please Note: The QRv2 is not backwards compatible with the original Beta-QR. QRv2 system requires a very specific groove design to function properly.
