I picked up a Faraday Flashlight just before my jaunt down to Breckenridge, Texas last weekend. We played with it abit there too see just how well it worked. We did not take it onto the range proper for yardage testing, but did get some decent range estimations back near the range house. Fifty (50) to Seventy-Five (75) yards seemed to be it's working limit. This light is a single LED flashlight, using a flat mirrored reflective surface and a magnifying lense. Pluses: Compact size in relation to it's ability. No Batteries required. Weight is comparable to a Mini-Mag w/batteries. Minuses: Clear, plastic body which allows reflected light back to highlight the user. Plastic lens cap. Granted, these lights come in several, transparent colors, I would paint the body to reduce reflective light and add a strip of tape around or glue the lense cap to the body to prevent it from coming apart in case of a hard knock or drop as is common with plastic flashlights. It does appear to be made from a heavy ABS plastic, which will make it rugged enough, once minor treatments are taken care of. This light was purchased at Walmart in the Fishing Department. There is also a 5 LED flashlight on the market. The price for either as I found them was under $15.00 each. Small price for not having to rely on batteries.
