The SureFire G3 LED ($92) is a bright idea in a seaworthy package. Its Nitrolon body is molded for a sure grip and resists weather and corrosion, thanks to O-ring seals. The LED provides extended runtime-nearly 9 1/2 hours-and never needs replacement because there is no filament to break or burn out. Disposable batteries mean it doesn't rely on the ship's electrical system to stay charged, which makes sense if you think about it. SureFire, (800) 828-8809; www.surefire.com
