The Supa-LED Triangle Worklight does two jobs: it is a bright area light for working at night and a red flashing warning triangle for roadside safety. Keep it in your vehicle and you always have both. It has four modes: 500 lumen white flood (about 2.5 hours), 200 lumen white flood (about 5.5 hours), 500 lumen white strobe (about 3.5 hours) and a 36 lumen red SMD strobe hazard light (about 7 hours). A built-in 180° adjustable stand doubles as a carry handle and lets it stand on its own, pointing the light where you need it. The tough housing has reinforced corner cladding. It runs on four AA batteries, which are not included.
