Hobbs marine lamps are completely weatherproof. They are totally sealed against moisture ingress, and the mounting hardware is stainless steel to prevent rust and corrosion. The housing is shock resistant and can withstand up to 6 G's vibration. Both flood and spot versions are available to meet your lighting requirements. The flood pattern illuminates an area 80° wide by 30° long and the spot pattern projects a narrow beam of light up to 1000'.
