If you like powerful flashlights, you’ve gotta get your hands on the Lumintop BLF GT. This beast of a torch pumps out 2,000 lumens and casts a beam a remarkable 2 kilometers long. You could use it as a searchlight, as a camp light, or as a fun experiment in your backyard (but be careful, as it packs a blinding punch). Made from hard-anodized aluminum, the light is IP65 waterproof and dustproof to keep the elements at bay. It’s also built with enhanced cooling fins to keep temperatures down. To control the light, it’s got a single side switch. Hold it down for a few seconds to get maximum output. If you hold it down shortly it steadily ramps up the power. Included with the light are spare O-rings, battery holders, a flashlight tube, a tripod buckle ring, and a tailcap.
