My old trusty Cygolight Roverthough a pretty bright light, it was very heavy system. Also after several years of use the NMIH battery isn't what it used to be. It doesn't hold the charge quite as long or burn quite as bright as it used to. It still works but it is getting toward the end of its lifespan. So enter the new light the Cygolight Dual Cross Pro Led Li-onthis light is a huge step up from my old light. not only is the light smaller , the battery is much smaller and lighter too. Where this light excels is in the amount of brightness they get from L.E.D's. It seems unreal how a light so small can put out so much light. I think I made a good buy...especially when it was on sale!
