He has good battery, so does he has good led light? Anyone has this? http://www.ebay.com/itm/HI-MAX-3xCREE-XM-L-T6-LED-Flashlight-Torch-FULL-SET-/220815901089?pt=US_Flashlights&hash=item3369a741a1#ht_6067wt_1037 Could it take just 1 battery? Look interesting. 
The design is nice, unfortunately it is a drop-in without the threads, totally unlike TF 3T6.
