the VB-16 Q5 came with 32 brightness modes, NO annoying SOS or strobe. The lowest low is extremely low and the high is very bright. It came with great built quality, uses forward clicky and memorizes your last mode. Comparing to my Ultrafire C2 CREE-P4 , it is much much brighter. Setting at just ~70%, it is still brighter than my Ultrafire C2 and my other p4 cree running Li-ion. The mode change interface is very simple, since it has 2 buttons (+/-) near the top of the light and a tail clicky to turn on and off.
Overall, I'm very impressed by this light, definitely strongly recommending anyone buying it.
