Looking at the make-up of my flashlights; could you form a concave cone (using the reflective side of the wrapper) around a chem light to direct or magnify its candlepower? at 200 yds a dull green light that is 3 inches across is better than one that is half an inch across. Try it sometime.. take a peice of alunimum foil and form it to the inside of a funnel. Take the foil out and place a chem light in the hole at the bottom of the foil cone. then hold a chem light by itself up in the other hand and see which one is brighter at 50 or 100 yds...
