I appreciate the fact that you take the time to make sure all your beamshots are aimed at precisely the same spot on that roof which makes it MUCH easier to compare beams, and get an idea of just how big the hot spots and spill beams are. Its amazing the difference in the size of the spill beam between the TK35 and the Barracuda. The Barracuda has a much tighter spill, whereras the TK35 has a very wide spill. Its easy to say that the Barracuda is a brighter light than the TK35, but we must remember that the TK35 U2 is an 860L light compared with an 1160L light in the Barracuda. Also, there's a big difference in tint between the Barracuda and the SR51. The SR51 seems pretty darn yellow, but maybe it just looks that way because the Barracuda is so white.
All in all, the Barracuda has a very tight beam, and therefore looks like it'll be a nice thrower. I really like the case it comes in too.
