Olight X6 Marauder 5000 Lumen Rechargeable LED Searchlight
This light is actually designed to be a professional rescue light. Even so, I couldn't resist putting it on this list, because it provides 5000 lumens of illumination, making it the most powerful searchlight I've seen. All that light is coming out of six LEDs, which are housed in an aluminum case and hidden behind a glass lens. The aluminum housing is machined to have cooling fins to prevent overheating. The battery pack on this unit is separated from the main body of the searchlight, and provided with a belt clip. That reduces operator fatigue, while giving a much larger battery capacity. The battery is Li-Ion for high charge capacity and long life While being a rechargeable unit, it will work powered directly off of home power. A power indicator is included, as well as a tripod mount. It will run a maximum of an hour and 15 minutes off the battery at its highest setting.
