well the effectiveness of the blinding trick is questioned many times. But from my experians people can see me after about 2 seconds after i blasted some light in there eye's at close range in almost total darkness.. (was a luxeon III light, so it's certainly not the most powerfull portable light)

cheaper company's sold in holland are brands like NEXTORCH, streamlight and nuwai on rare occasion. There is a also the "police" brand which in my opinion is a piece of junk.
