the luu lights are quite different , most notably coming with an extra CNCd 4AA Battery case that you screw into the back of the CNCd body when you want / need to switch to AA battery power. Im not the worlds number one light expert but Ive never seen this feature before , its very james bond man from the golden gun .
Each Luu comes standard with full CNC main body and also the CNC AA Battery case as does the 3 pc multi filter set , 4 cell li-ion battery , helmet mount .
more details and beam patterns on the on-one site early next week
