Glowstick
Plastic tubes contain chemicals that create illumination when mixed together (usually by shaking, twisting, breaking open a part of it). Glowsticks come in a variety of lengths, from a few inches to a foot or more. Though they're not reusable and can't be turned off, but are: cheap, light, wind and waterproof, and don't need batteries. And they're immune to supernatural effects that disrupt electronics. Several small or one large glowstick affects tasks performed in darkness in the same way as a single flashlight, as long as the action takes place within its circle of illumination (about 3 yards in diameter). Novelty-grade glowsticks last 1-3 hours; law enforcement / commercial types can last up to 12 hours. Glowsticks that emit infrared light, and hence can be used with IR-sensitive imaging systems, are available to law enforcement, the military, or from gray-market sources.
