Fenix makes an awesome little light that strobes (180+ lumen) - check their store out here. I got to play with the P2D this weekend and I'm definitely ordering one - blindingly bright, small enough for keychain carry, and the strobe function is highly disorientating (though it's not a fancy "special" strobe like Gladius makes). The prices are pretty competitive, too ($50-100 depending on model and options).
