I am going to nights for the first time in 4 years. My old Magcharger and G2L seem outdated. Researching the newest generation of options makes my head spin. So......please discuss; What light(s) meets the following criteria? 1) Long run time (one charge or set of batteries should last AT LEAST a 12 hour shift) 2) Cheap to run (rechargeables have the edge, but what are the options and how long does it take for a full recharge?) 3) BRIGHT (200 lumens seems to be a good starting point, with the possibility of 500 or 700 or more) 4) Small size, light weight, and durability 5) Simplicity (I like ON/OF, with maybe, 1 or 2 lower settings to conseve battery life or avoid blinding oneself inside. I don't want to push some long convoluted combination of buttons to get the thing on/off). Any input on these specific lights?
