The Underwater Kinetics 4AA RFL and 4AA Surefoot are revolutionary and powerful LED work lights. Certified for use in explosive environments (Zone 0 + 20), these extremely robust lights help make your work safer at a very attractive price. The 4AA Surefoot offers special advantages with its dual beam. The main beam (170 lm) is focused and directed forward for bright, precise illumination. A second light cone (20 lm) emerges from the side of the lamp head and is directed downward. This makes obstacles on the ground, uneven surfaces, and other trip hazards in front of you more visible. Documents, plans, and similar items can also be illuminated without glare using this additional light.
