The tighter the beam the brighter the light will look.
Many of those 1 million, or 30 million candlepower lights really only measure 200,000 to 300,000. Streamlight has the only true "1 million" I have seen in a protable light, but it is pretty big. Streamlight has something called a Waypoint, which from what I have read in reviews, creates a really long distance spot, somwhere north of 100,000 with a LED light source. (Their factory is up the road from where I live).
Regardless of who you buy the light from, make sure the manufacturer rates their product to the ANSI flashlight standards, so you can be sure that what they claim is real and not pulled out of the air like txdon's $10 light.
