I've been sitting on this project for a while. It's been about six months in the making. I just applied for a patent, so now I can show you some photos of the world's first Quick-Release Key Chain Flashlight! The images below are "beta" prototypes and fully functional. More than likely, the production versions will be offered in Type III hard anodize (with knurling) and Electroless Nickel (with fine flutes or smooth head) to match my other offerings.
If you are interested in seeing this light make it to production, please post a comment below!
The new light is just over 1/2" in diameter and 3" long, not including the QR portion. In keeping with the Prometheus focus on high-quality "usable" light, this model will feature the 92+ CRI Nichia 219 LED (4500K neutral white). This means it won't have the most output of "any" AAA light, but it will have superior color accuracy for when you really "need" to have some extra light. I'm not aware of any AAA light on the market that comes standard with the 219, but the light quality is nothing short of spectacular.
Output is expected to be around 70 lumens with two modes, "moonlight" and full power. "Moonlight" is a flashaholic term for really-low and is excellent for use with night-adapted vision. On high, this little wonder is still as bright as the old incandescent "cop" MagLite that takes two D cell batteries. Did I mention it fits on your keychain?
