The most exciting to me is the Sentinel WS1. It is the same size as the Surefire XC-1 (perfect for unobtrusive carry on a G19) but with three times the output (200 lumens vs 600 lumens). The battery is rechargeable via USB without removal, and the switches are programmable using your smart phone/tablet via Bluetooth. I do hope the batteries are also replaceable. Recharging is great and all, but if I need fresh juice now, I need it NOW.

The other light I can't find much about... I'm not sure if it's just a proof of concept, or tech demo, or something they actually want to bring to market. I do know it's tiny.
