170 lumens, 35 bucks.
I just got one. I wouldn't call it bright enough for "tactical"/dazzle use, but its damn bright and has a strobe mode.
IMHO-Bright enough to disorient, not bright enough to "dazzle". If I had the money Id get something in the 500 lumens range. Something that semi-permanently knocks out vision. But for $35 Vs $200...
On the other hand...
$155 bucks, 500 lumens
. This will blind an attacker.
