do not get I wrong , I use a MiniMag for year , but then I be give a Pelican Versabrite . while the original Versabrite be not as bright as the MiniMag -lrb- and no focus -rrb- , it have a tiltable head and build in clip to mount to a hat brim or shirt pocket - useful feature when you have to inspect thing and take note at night , or otherwise need light and need both hand free . the Versabrite II end the controversy . it be brighter , no matter how the the MiniMag be focus .  by the way , for a keyring light , try one of the coin-sized led light like the Photon Microlight . they be amazing .
