Energizer's rugged Night Strike LED flashlights, available in "Compact" and "Swivel" editions, offer 40 and 100 lumens respectively from double-AA batteries. Apart from white light, each waterproof design has multiple colored LEDs and can survive a claimed 10' drop.
The smaller model, light enough to clip onto the bill of a baseball cap, has green, red and blue LED lights, eight hours of runtime from a single lithium battery, and a "find me" setting that flashes the green LED once every half-second.
The larger model also has an ultraviolet light, a swiveling head, and can run on one or two AA batteries. A three-position lever switches between UV, visible spectra, and a 'locked' position, which prevents it from being turned on or off.
The compact model is powerful and feels much more rugged than most miniature flashlights. The swivel model's lever and size makes that version relatively unweildy, but it's far brighter and no more pricey. Both offer features that everyday users won't ever need, at considerable expense–$80 each–so they're best considered as flashlight 'tools' for those with a real need for the extra colors or durability. For the rest of us, there's just no reason to get them, at that price, unless you're dying for the looks.
