Powertac E5 4th GenerationWeapon KitIntroducing the latest upgrade from Powertac, the fourth generation E5 flashlight. Now in a complete weapons package, this kit is the perfect choice for law enforcement, military personnel, hunters, search and rescue teams, and other tough or hazardous tasks. The fourth generation E5 is now fitted with a CREE XM-L2 LED and outputs a blinding 980 lumens, with a maximum run time of up to 706 hours, when in Firefly mode. Measuring in at 5", the E5 is machined from aerospace aluminum alloy with a hard anodized finish, making it compact and lightweight. The 1" diamond-cut knurled body allows for the E5 to be mounted to a weapon for those tactical missions. No need to purchase extra mounts or switches, as this kit includes an off set weapon mount and pressure switch. The easy to use user interface allows you to cycle from the 980 lumen High mode all the way down to the subtle 2 lumen Firefly mode. Powering the E5 are either two Lithium CR123A batteries or a single rechargeable 18650 battery, making the E5 truly versatile.
