I came across this company a while back and i have two of their lights,they have been extremely bright and reliable lights for a fraction of the price of a Surefire
They are the Solarforce L2 350lumen light with a crenulated bezel. The one shown is the 2 cell 123 lithium version, i also have the L2m which is the 1 cell version, still 350lumen. I have the L2m mounted on my AR. They are available with a end cap switch and or a pressure pad switch
