River Rock Designs, Inc. has introduced the Perfect Circle, a palm-size, highly-focused flashlight. 

The flashlight from the Austin, Texas,-based River Rock Designs arrives with a weather-proof O-ring and an anodized aircraft-aluminum body.  

The Perfect Circle flashlight is built with precision-formed lens that projects a precise, focused hard edge yet soft full-moon-shaped light beam. It's ideal for close up inside and outside activities and yet provides illumination greater than tiny flashlights or keychain lights, according to the company. At 20 feet, during company testing, the little light projected a 41-inch circle of light.

The Perfect Circle Flashlight can also emit a constant hands-free flash (about 80 flashes per minute) for signaling.

"The Perfect Circle is especially handy where you simply want to see what you are doing or where you are going without blinding yourself or others with too much power," said John Sedovic, president of River Rock Lights. "In fact in some cases it might make a very handy tactical map light, purse or backpack light."

The light will retail for $14.99 and includes one AA battery.
