Two clever devices blended into one super useful gadget, a four function (high, low, strobe and signal) focused, bright white water resistant LED with an effective range of 50 feet and one-mile visibility, combined with a durable, flexible 18” rubberized gear tie for attaching, hanging, or positioning the light at almost any angle imaginable (because sometimes you need light in remote, awkward, or hard to reach places). 6 Lumens (high - 10 hours)/1 Lumen (low - 22 hours). Two 3V Lithium batteries included. 5.5"×3.1"×.50". .85oz.
