Each SMX154 fixture is rated at roughly 7,000 verified lumens (around 15,750 total combined lumens across the RGBW LED array) with a 90 deg beam angle, and supports Lumishore's full EOS RGBW colour-change system -- meaning the lights can shift through a full colour palette, not just fixed white or blue, controlled from a compatible chartplotter MFD, a smartphone app, or the included LUX Command Center display. Build quality is aimed at permanent underwater installation: a marine bronze fixture body, borosilicate glass lens, and an IP68 water-ingress rating for genuine continuous submersion, backed by a 3-year warranty and a typical LED service life rated at 50,000+ hours. The kit is designed for surface mounting on stepped hulls, transoms, or side hull sections, and Lumishore's light-discovery/auto-install function is built to simplify commissioning multiple fixtures on the same hub without manual address configuration. The '60-0537' part reference and 'LS' designation in this listing correspond to Lumishore's own part numbering for this specific 2-light/hub/command-center bundle configuration, as opposed to single-light or larger multi-light SMX154 packages Lumishore also offers.
