Interesting. I've ordered several flashlights and a couple of LASERS from DX and the average delivery time is between 10 and 14 days. 3-6 weeks doesn't sound right at all, unless an item is on backorder.
Im on the east coast, that always adds a week to the shipping time.
Also I got my light today. Very well built. Single AA isnt bright at all. Single cr123 is bright. The 2 X AA is about as bright as the cr123. But none of them are the rated 120 lumens. I would guess its about 75 lumens. Doing a runtime test now. Ill post results later.
EDIT - Im 2.5 hours into a runtime test with no noticable drop in brightness. Im using one panasonic cr123. Battery reads 2.30 volts after 2.5 hours. Pretty impressive.
EDIT - After 3.0 hours the light has dropped below 50% the battery reads 1.25 volts. Still plenty of useful light. Ended the test here.
