There are handheld flashlights today that are more powerful and shoot a nicer beam (without hotspots or "holes") that are only slightly larger (fatter, mostly) than a 2 AA cell Maglite. You can do a little research on
www.candlepowerforums.com. I used to do reviews on that site but I haven't been on there much lately. I like the FENIX brand lights - some of them have built in strobe and SOS functions. There are many others but you can't go wrong with Fenix for choice and simplicity. The only thing that turns some people off are the batteries some of them use. You CAN find good ones that take AA batteries but the ones that are the most "fun" use either the one time CR123 cells or rechargeable "18650" cells. You can buy the 18650 cells for $5 to $12 each and a charger (which you'll need because they are lithium ion) for $10 to $20. The CR123 cells are cheaper online or in a gun store than anywhere else. That is the way to go for a seldom used light. The rated shelf life of the batteries is 10 years. Frequent users should go rechargeable.
I'm not exaggerating. . . one handheld light smaller than a 2 C cell light will throw the same amount light as a car headlight or MORE! I plan on using a Fenix TK-40 (discontinued but replaced by the 45 or higher) as my dedicated light on the boat. It's a little larger because it holds 8 AAs but it will run on high for many hours and puts out an insane amount of light and has the SOS feature.
