The Twin-Task line of flashlights offers a patented LED/Xenon combination so you can choose between a super bright light (xenon) and an incredibly long runtime (LED). Flashlights are ideal to use in a wide variety of applications, including school, automotive, security, and household, even recreation. And no matter what task you're performing, you'll find them remarkably durable. All are constructed of computer-machined aluminum with an anodized finish, are 0-ring sealed, feature an unbreakable polycarbonate lens, and are water resistent.
