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 1,000'.
