My 1996, 2C, blue, superpeli, is the most tightly focused light I have. At 2.2 watts with minimal spill it's not good for many purposes but it's unique.
No blue, but the M4 (I think it's an M4) really does have a tight beam. It's not overly bright, but is the closest to laser-like I've seen. It's rechargeable too. /ubbthreads/images/graemlins/thumbsup.gif Any chance of a beamshot?
