yesterday I bought a princeton tec impact.<br>it was marked down in the shop (from £30 to £7.50!!! I think the people in that shop are mad) it use's just one LED and is powered be four AA's, it says on the packet "projects a beam 50 + yards". I can't say if that's exacly true or not but it was a good beam. Aprently it use's some sort of opticley enhanceing lense. 150 + hours of burn time. <br>it came with a nice lanyard as well. And life time warenty, I think I got a good deal!<br>-james <br>
