Description XFM models, or Xchangeable flush-mounts, are just that – they’re exchangeable without hauling should servicing or upgrading ever be needed. Their exceptionally low profile head offers virtually unlimited hull mounting options. Can be retrofitted into most existing underwater lighting hole cut-outs. Suitable for all hull types up to and over 65 ft (20 m) using 2 to 6 lights with spacing of 3 to 5 ft (1 to 1.5 m). For metal hulls, add the Delrin Isolation Sleeve accessory. Deutsch plug and play quick connectors make this light a quick fit. Maintenance is easy, just wipe away marine growth from its scratch resistant Titanium™ glass lens. Three super bright LED color options.
