Googleotomy, if you have a small DC incandecent lamp, it is shining in pretty much all dirctions, right? If you put the bulb into a tube, like a toilet paper tube, then the light coming out the other end will be a spot, correct? The tube is causing the bulb to act like a spolight, even though i is not a spotlight.
Are you really this dumb, or are you just acting dumb?
