The UCO StakeLight is a unique tent stake with a built-in LED light to provide area lighting around your tent. The 17 lumens of light can help you locate your tent in the dark and alert campers to the presence of tent guy lines. Switch to strobe mode to help locate your tent over longer distances in the backcountry. The StakeLight LED provides up to 10 hours of continuous light or up to 24 hours of light in the strobe mode. Each StakeLight is powered by 1 AAA conventional battery (sold separately) and is encased in a highly water-resistant TPE housing (IPX 6). The StakeLight is constructed from durable, lightweight 6000-series aluminum. Each stake is 9-Inch long and weighs just 1.3 ounces (36g) without battery.
