Ideal for new installations or replacing existing fluorescent fixtures, these lights feature a 30,000+ hour LED life, watertight polycarbonate tube, and quality anodized marine grade aluminum housings with a power draw of less than 1 amp. The cool white 120° LED's create a clean, non-glare flood-like illumination for night boating. Switch from all-white light to all-red or all-blue while under way to provide the needed task lighting while preserving night vision. 12vdc.
