I pieced together an inexpensive Surefire clone out of a Solarforce L2 body & tail switch (sized for 18650 battery), and a Cree XML (U2) drop in, 5 mode. The Li-ion batteries showed up today so I did a little test. These things are crazy bright. The lights in the pictures below are 1) 3xD-cell Maglite , 2) 2x AA-cell Maglite w/ 1W LED and IQ switch upgrades, 3) P60 clone w/ XML LED and 18650 cell.
no comparison. crazy bright!
