I have orders shipped on 19 september and not arrived (from HK). Also orders from 23 september (1 month!!!! and DX CSE says that I have to wait at least 2 weeks more!)
Just joking. I orderd two and I don't care if it turns out to be crappy. I have some spare LEDs (Q3, Q5, R2, R5) and some driver boards laying around here.
I would wild guess they are getting rid of an extremely old stock with P4 or other rejects from manufacturers. Still, can't beat the price. Whole flashlight for way less than a good 18650 cell.
Probably low powered P4 (around 0,6A on max) with greenish tint is my guess. But you can get q5 of ebay for 3,2$ delivered and mod the light for DD at ~1A.
